Rating Scale

5.0: Unconditional must-pick, brings an almost game-winning advantage
4.5: Unconditional must-pick in the right color pair, brings a large advantage
4.0: First-pick quality, extremely synergistic with the color pair’s theme, can be the deciding card for splashing / switching colors or entering a color pair
3.5: Top uncommons and commons of the set and other cards strong enough, synergistic with the color pair’s theme, can be a key card for entering a color pair
3.0: Important cards for the color pair’s theme, and other above-average cards you’ll want in your final deck
2.5: Average, usually a decent curve filler
2.0 to 1.0: Below average, generally not played, can be used as filler when necessary but not in excess
0.5 to 0.0: Unplayable, basically never play it; it will only help you lose

Ratings

Score: 3.0
Comment: Choosing the first mode lets you launch a strong attack; the second can protect your creatures, and with lifelink it can gain you a big chunk of life. Both options are very useful in limited.

Score: 1.5
Comment: A card that is too defensively oriented; it is only useful when played at the very, very end, and drawn early it’s a dead card stuck in hand. In addition, this set’s black has many life-loss cards that can bypass this card’s protection and still kill you at end of turn.

Score: 2.0
Comment: The ideal situation is to build a board first, then blow up all the lands on both sides, leaving the opponent with no way to fight back, and push them to death with your board. But if the opponent’s board is stronger than yours, this card becomes a complete dead card. Aggro-oriented builds can start applying board pressure early and should be better suited to it.

Score: 2.5
Comment: Although casting it requires sacrificing a creature, making all your creatures indestructible for a turn and putting +1/+1 counters on all of them is pretty good.

Score: 2.0
Comment: This set has no graveyard-related theme, so the efficiency may not be very high. If the deck has powerful creatures costing three or less, you can consider it.

Score: 3.5
Comment: A sorcery that makes three 1/1 token creatures, and it pairs very well with other cards in this set, for example Aziza, Mage Tower Captain.

Score: 2.5
Comment: A heavily restricted universal answer that really tests a deck’s color-fixing ability; the more mana of different colors you can produce, the more power it shows.

Score: 2.5
Comment: An instant-speed answer that kills creatures with power 4 or greater or toughness 4 or greater, and it costs only two mana. Although it has a range limit, it is still decent removal.

Score: 2.0
Comment: Very timing-dependent in use; after all, holding up two mana to disrupt the opponent’s tempo sometimes ends up disrupting your own tempo first.

Score: 2.5
Comment: Artifact and enchantment removal that can also pump your whole team, so you can choose flexibly according to the situation.

Score: 1.0
Comment: It can only dig back creatures with mana value two or less, and there are really too few things it can fetch; only an extreme aggro deck stuffed with low-cost creatures has a chance of playing it.

Score: 4.5
Comment: Two-mana creature removal, but it helps the opponent find a land to ramp. Cast with Overload, it is a one-sided sweeper; once it resolves, the game is probably about to end.

Score: 0.5
Comment: Storm in limited usually doesn’t stack very high, and this card alone shouldn’t be able to mill the opponent out directly.

Score: 4.5
Comment: Temporary removal that can bounce any nonland permanent of the opponent’s. Cast with Overload, it bounces all of the opponent’s nonland permanents instead, leaving only lands on the opponent’s board, a very powerful one-sided soft sweeper.

Score: 1.5
Comment: It lets you return an Island to hand to cast it for free, occasionally countering the opponent by surprise. But the timing is still harsh in use, since the opponent only has to pay one more mana.

Score: 2.5
Comment: It can be treated as a two-mana draw-one split into two parts; use it to draw cards when you have spare mana, and it will be a nice lubricant in the deck.

Score: 2.5
Comment: Although it is a counterspell with a restricted range, being able to counter expensive spells for only two mana late in the game can always catch the opponent in limited.

Score: 1.0
Comment: The range limit is large; it can only counter sorceries or instants, so it only has a chance as a sideboard card if the opponent has powerful sorceries or instants.

Score: 3.0
Comment: You can pay 1 life and exile a blue card from your hand to cast it for free. In certain key situations, it can force a two-for-one against the opponent. Of course, late in the game with enough mana, spending five for a straight Counterspell is fine too.

Score: 3.0
Comment: A rare piece of blue removal; after the kill, the creature’s controller makes a 3/3 vanilla creature, and it can also kill your own small creatures to turn them into board pressure.

Score: 3.5
Comment: It can look at up to the top three cards of the library, a very efficient card-filtering tool, deep enough when you need to find key cards.

Score: 3.0
Comment: Slightly inferior compared to Preordain, but still an excellent card-filtering tool.

Score: 2.0
Comment: With just one blue mana you can interfere with the opponent’s noncreature spells, and the efficiency is still quite good. It’s just that the more lands there are late in the game, the more this card’s influence gradually fades.

Score: 4.0
Comment: Looking at five and taking two is simply too good in depth; drawing it at any time gives a good card that earns you resources.

Score: 0.5
Comment: A high-risk card-draw tool that may flip its way into killing you; use it with discretion if you want to gamble on your luck.

Score: 3.0
Comment: Discarding a card or paying 3 life is a bit of a steep price in limited, but whatever you say, it’s still removal.

Score: 1.5
Comment: You need to have a creature to sacrifice and a spell in hand to cast for this card to be useful. And what it produces is four black mana, so it has quite a few restrictions.

Score: 3.5
Comment: With Phyrexian mana, you can flexibly choose whether to pay life or use black mana to cast this spell; at minimum you only need one mana of any color plus four life, and the freed-up mana lets you do something else. In addition, -5/-5 can bypass indestructible protection, making it very powerful removal.

Score: 2.5
Comment: Although it can kill a creature or tear down an enchantment, the price is losing life equal to the target’s mana value, so watch your life total when using it.

Score: 1.5
Comment: You have to spend four first and only get the effect after three turns, and when casting it you can’t guarantee whether the opponent’s or your own graveyard is stronger, so it’s too unstable to use. Note the new Suspend rule here: after the countdown finishes, you can choose to leave this card in exile instead of casting it, which you might do when the opponent’s graveyard is stronger than yours.

Score: 2.0
Comment: It can catch the opponent off guard a bit in creature combat, and when you don’t need it you can still spend a little black mana to cycle it so it doesn’t clog your hand.

Score: 2.5
Comment: Making the opponent sacrifice a creature can sometimes bypass certain protection, but if the opponent has multiple creatures on the board it is worse than ordinary removal; being able to answer planeswalkers is a small highlight.

Score: 2.0
Comment: Both players lose 1 life, discard a card, sacrifice a creature, and sacrifice a land. The timing is subtle, so calculate carefully who benefits more before casting it.

Score: 3.0
Comment: Both the depth and the number of cards dug are quite good; the more mana you spend, the deeper you look and the more cards you take. The downside is losing life.

Score: 4.0
Comment: For one mana and 2 life you can put a card you want on top of the library, and at instant speed too. It’s really strong: get whatever you need.

Score: 2.0
Comment: This set has no graveyard theme, so digging through the graveyard may not be efficient. Moreover, this set’s discard theme is red-white, so to use this card you’d have to pull in an extra color.

Score: 3.0
Comment: Dealing 3 damage is already excellent creature removal, and occasionally it can be used to destroy an artifact.

Score: 3.0
Comment: Discard a card, draw two cards, and get two Treasures; a very nice card-filtering tool.

Score: 3.5
Comment: The first mode sweeps the board and can sweep planeswalkers too, which leaves nothing to complain about; the second mode can sweep about two-thirds of this set’s artifacts, so the range is still wide.

Score: 3.0
Comment: It lets a creature deliver a burst punch, and can be used again with Flashback.

Score: 3.0
Comment: Whether it’s dealing 2 damage for one mana or, with Kicker, dealing 4 damage for five mana, it’s great removal and can also serve as a final finishing tool.

Score: 3.0
Comment: Removal and a finisher that get stronger the later the game goes. X=1 deals 5 damage to one target; X=2 deals 10 damage to each of two targets, which takes off half the opponent’s life; X=3 deals 15 damage to each of three targets, which almost kills the opponent outright.

Score: 2.0
Comment: Cast directly, it’s just four mana for two 1/1s, which is a bit too bad. At least with one storm count first, making four 1/1s is worth the cost of this card. But building up storm count before casting this card usually can only be done late in the game.

Score: 2.5
Comment: The first mode only has a chance to ramp in the early-to-mid game, and is completely useless late when the opponent has few cards in hand; the second mode exiles the top three cards of the library but they can only be used this turn, because you must first spend three mana to cast this spell, so if you don’t have much mana left and flip poorly, those cards are wasted.

Score: 3.5
Comment: The strongest combat trick, bar none; the permanent pump and trample from the Monster Role token are still too strong in limited.

Score: 2.0
Comment: Going from two mana to three isn’t completely useless, but you need to happen to have an outlet that can use that mana.

Score: 3.0
Comment: The first mode’s range of copyable targets is very broad, including instants, sorceries, activated abilities, triggered abilities, and it isn’t even restricted to your own, so you can copy the opponent’s too; the second mode, redirecting the target of the opponent’s single-target removal, is a big win. If you have enough mana to do both modes, that’s a huge win.

Score: 4.0
Comment: Super strong red sweeper; X can be flexibly adjusted to the board state. X greater than 4 also removes all artifacts, and X greater than 8 gives you a giant 8/8 vanilla after the sweep.

Score: 4.0
Comment: Makes as many 1/1 tokens as X, and these tokens are all lands that can produce mana, which can achieve a terrifying ramp effect.

Score: 3.0
Comment: Used on offense, it lets your creature deliver a huge trampling punch, but you must sacrifice that creature at the end step. It can also be used on blocks, and when used to block you don’t need to sacrifice the creature. Incidentally, it can also be used on the opponent’s creatures as removal: after taking a hit of double damage, that creature is sacrificed at end of turn.

Score: 2.0
Comment: Sacrifice a land to find a land; you’d only want to play it if the deck has utility lands or you really need color fixing.

Score: 2.5
Comment: A decent combat trick that works on both offense and defense.

Score: 1.5
Comment: In limited you cast at most one or two creature spells a turn, and you have to spend one mana first to cast this, so the efficiency is poor.

Score: 3.0
Comment: Putting +1/+1 counters on your creature and then dealing damage one-sidedly is much better than fighting.

Score: 2.5
Comment: A highly efficient targeted sideboard card that satisfies three wishes at once; use it as a sideboard card depending on the situation.

Score: 2.5
Comment: Gives hexproof to protect a creature for a turn, and the attached Royal Role token also permanently pumps the creature; ward 1 also forces the opponent to spend more to remove it later.

Score: 3.5
Comment: Draw a card for each creature you control, and gain 4 life for each creature with power 4 or greater; it refills your hand and saves your life at the same time.

Score: 3.0
Comment: A good card that ramps by skipping ahead in mana, and can also be used for color fixing.

Score: 2.5
Comment: Giving only +1/+1 doesn’t pump enough, and this turn your creatures can’t deal combat damage normally because of Infect, so if you can’t put ten poison counters on the opponent in one go, this turn’s attack has no meaning at all. But if your board is strong enough, you can indeed use the trample this gives to break through the opponent’s defenses; if you lack finishing tools you can consider it.

Score: 2.0
Comment: Protection only against blue and black; consider it as a sideboard card when the opponent has many blue counterspells or black removal spells.

Score: 2.0
Comment: If it is successfully cast, you should at least be able to pull a two-mana creature, instant, or sorcery from the library and cast it for free; the more colors a deck plays, the more it will want this.

Score: 2.5
Comment: It can only sweep nonland permanents with mana value two or less, so the range is still too narrow; against an aggro deck you might swap it in depending on the situation.

Score: 2.5
Comment: It can reflect once the damage dealt to a player by the target source, especially against red spells’ direct damage, or you can choose not to block when an opponent’s creature attacks, take it to the face, and then use this card to reflect the damage back at the opponent.

Score: 3.5
Comment: A powerful card-advantage spell; for just two mana you look at the top three cards of the library, one goes to hand and one goes to exile, usable this turn. The common play is to put a spell in hand and a land in exile, then play them out this turn.

Score: 1.5
Comment: A targeted answer with heavy color requirements; use it as a sideboard card depending on the situation.
