Traditionally filled with flyers, counterspells, and massive leviathans, blue cards in Magic: The Gathering are considered some of the most powerful in the game. With March of the Machine and the introduction of battle cards, there are some unique approaches to blue cards.
Many of the best blue cards feature convoke, a mechanic traditionally found on white and green cards that allows you to tap your creatures to pay some or even all of a spell’s mana cost. Among the best blue cards are several cards that change, some can draw you tons of cards and others help control the board.
10 Epharina dispersion
Ephara’s Dispersal is a versatile tempo spell that can be technical to keep your opponent’s best attacker off the board or remove a creature that’s giving you trouble for a turn or two. Even better, Ephara’s Disperal becomes cheaper if you target an attacking creature, reducing the mana cost by two generic mana.
As a one-mana bounce spell that also controls 2, Ephera’s Disperal is an incredibly high-value spell that fills your graveyard with spells you can bring back and moves between cards you don’t need from your deck.
9 Zephyr Singer
An unusual creature that breaks traditional color trends, Zephyr Singer is a blue creature with convoke that allows you to tap creatures to help pay the mana cost. Each creature you touch to play Zephyr Singer gains a flying counter. On the next turn, you suddenly have an army of flying creatures that you can attack with Singer.
The ability to fly is seen on all blue cards, but vigilance is relatively rare, though not unheard of. You’ll need a creature-heavy deck to take advantage of Zephyr Singer, but it could also work well with token-generating cards.
8 A transcendent message
Another blue summon spell, but this time your creatures can help you draw tons of cards with this instant spell. Transcendent Message costs a staggering four blue mana and then X.
Your creatures can be tapped to pay both X and blue mana cost if the creatures you tap for blue mana are themselves blue.
Transcendent Message will likely be played more in Commander than in other formats, as the ability to draw a ton of cards even if you tap all of your lands is very strong. There are plenty of opportunities to use your creatures to draw cards before the board wipe resolves, or in response to blocking an incoming attack where you can lose a bunch of creatures in combat.
7 Complete the round
Another summon spell, which is good, since spending six mana right now can be a bit mana intensive for most decks. Complete the Circuit allows you to cast sorcery spells as if they had a flash, allowing you to cast them at instant speed.
You must then copy the next spell you cast twice, giving you a total of three spells on the stack and allowing you to choose new targets for the copies. With Complete the Circuit, there’s a ton of room to explore, as casting wizard spells changes how they interact with the game in a flash.
6 Invasion of Segovia // Caetus, Sea Tyrant of Segovia
The first blue battle card among the best blue cards from March of the Machine, Invasion of Segovia is a silly card that has a powerful effect when transformed. When it enters the battlefield, you get two 1/1 Kraken tokens with trample that may do little on their own, but have the potential to do big things.
When he morphs into Caetus, Sea Tyrant of Segovia, a massive (for Segovia) 3/3 Leviathan that allows all of your creatures to summon spells. Caetus also helps you cast those non-creature spells by untaping four creatures of your choice on the end step, giving you a chance to cast instant speed spells with your creatures or even restore your board after tapping.
5 Chrome Host Seedshark
A much more traditional blue card comes in the form of Chrome Host Seedshark, a flying shark that gives you an Incubator token every time you cast a non-creature spell. Add +1/+1 counters equal to the spell’s mana value to the incubator token.
Seedshark is a Phyrexian version of the Shark Typhoon spell from Ikoria: Lair of Behemoths. Mechanically, Seedshark does very similar things for less mana, although the tokens you create have a mana commitment before you can start attacking with them.
4 Rona, Herald of Invasion // Rona, Tolarian Obliterator
Rona has had a few cards printed since her introduction back in the Dominaria deck, but her latest iteration is the scariest yet. Rona, Herald of Invasion is a powerful legendary archetype spell that allows you to open her whenever you cast a legendary spell.
Transforming Rona costs a hefty six mana, and in return you get a new version of Phyrexian Obliterator. When Rona, Tolarian Obliterator takes damage, the controller of that resource randomly banishes a card from their hand, and if it’s a land, you can put it into play, or if it’s something else, you can cast it for free.
3 Invasion of Arcavios // Invocation of the Founders
Another battle card on this list is Invasion of Arcavios, a very powerful spell-based siege that teaches spells and doubles anything you play when it changes. When Invasion of Avcavios enters the battlefield, you can teach an instant or sorcery either from your library, graveyard, or out of play, allowing you to search for a card on the sideboard.
Once you get rid of all of his defensive counters, he turns into a charming Invocation of the Founders. Any instant or spell you play is doubled by that spell in the game, giving you all kinds of copies to wreak havoc with.
2 Jin-Gitaxias
There is so much going on with the new Jin-Gitaxias that it is hard to comprehend. First off, Jin-Gitaxias is naturally hard to deal with since he has Ward 2 guarding him. It then gives you a full hand by allowing you to draw cards when you cast any non-creature spell with a mana value of three or more.
When you turn into The Great Synthesis sage, you draw even more cards for the first chapter. Another time, you can return all non-Phyrexian creatures back to their owner’s hand, even your own.
Then, when the final chapter comes around, you can cast any number of spells from your hand for free and return the Grand Synthesis to Jin-Gitaxias.
1 Elf Master
Faerie Mastermind is a card drawing machine based on Magic World Champion Yuti Takahashi. The main ability you’ll want to watch out for is that every time your opponent draws their second card on the turn, you draw a card.
You can put Faerie Mastermind into play for just two mana, allowing you to cast it in response to an opponent’s spell or ability that allows them to draw another card and you draw a card right next to them.
