Traditionally filled with flyers, counterspells, and massive behemoths, Magic: The Gathering’s blue cards are considered some of the most powerful cards in the game. With the March of the Machine and the introduction of combat cards, there are some unique approaches to blue cards.
Many top blue cards have muster, a mechanism traditionally seen on white and green cards, allowing you to tap a creature to pay some or all of a spell’s mana cost. Some of the best blue cards have several that can transform, some can draw tons of cards, and others help you control the board.
10 Dispersion of Ephara
A versatile tempo spell, Ephara’s Dispersal can be a skill that knocks your opponent’s best attackers off the board or removes a troublesome creature from the board for a turn or two. Even better, Ephara’s Disperal has a lower cost if it targets an attacking creature, reducing its mana cost by 2 normal mana.
Ephera’s Disperal, a 1-mana bounce spell that watches over 2, is an incredibly valuable spell, filling your graveyard with spells you can bring back and converting cards you don’t need in your deck.
9 zephyr singer
An odd creature that breaks the traditional color trend, the Zephyr Singer is a blue creature with a muster ability that can be tapped to pay its mana cost. Each creature you tap to cast Zephyr Singer gets a flying counter. You suddenly have an army of flying creatures to attack with Singer on your next turn.
The ability to fly is found all over the blue cards, but borderline is relatively rare, though not unheard of. You’ll need a deck with lots of creatures to take advantage of Zephyr Singer, but it can also work well with cards that generate tokens.
8 transcendent message
Another blue muster spell, but this time a creature can help draw tons of cards from this Instant spell. Transcendent Message costs a whopping 4 blue mana plus X.
As long as the creature you tap for blue mana is itself blue, you can tap a creature for both its X mana cost and its blue mana cost.
Transcendent Message is likely to be played more often in Commander than any other format, and the ability to draw tons of cards even when all lands are tapped is very powerful. There are countless possibilities for using creatures to draw cards before board clearing resolves or in response to blocking incoming attacks that can cost you a lot of creatures in combat.
7 complete the circuit
Another muster spell is good because it can be a little mana intensive in most decks since it costs 6 mana at this moment. Complete the Circuit allows you to cast magic spells as if you had a flash of light, making them instantly cast.
You can then copy the next spell you cast twice, giving you a total of three spells on the stack and choosing a new target to copy. There are tons of possibilities to explore throughout Complete the Circuit, as flashing magic spells changes the way you interact with the game.
6 Invasion of Segovia // Caitus, Sea Tyrant of Segovia
The first blue battle card in March of the Machine, the blue battle card Invasion of Segovia is a goofy card with powerful effects when transformed. Upon entering the battlefield, you gain two 1/1 Kraken Tokens with Charge. This token can do little on its own, but it has the potential to do great things.
Segovia’s Sea Tyrant, Segovia’s Sea Tyrant, after transforming into a giant (for Segovia) 3/3 Leviathan that summons all non-creature spells. Caetus also untaps 4 creatures of your choice in the end step, giving you a chance to cast an instant speed spell with them, or recovering the board after tapping out to help you cast non-creature spells.
5 Chrome host Seedshark
A far more traditional blue card comes in the form of the Chrome host Seedshark, a flying shark that grants you an incubator token whenever you cast a non-creature spell. Add a +1/+1 counter equal to the spell’s mana value to the incubator token.
Seedshark is the Phyrexian version of the Shark Typhoon spell from Ikoria: Lair of Behemoths. Mechanically, Seedshark does a very similar job for less mana, but the tokens it creates have a mana commitment before launching an attack.
4 Rhona Herald of Aggression // Rhona the Tolarian Destroyer
Rona has printed a handful of cards since reappearing in the Dominaria set, but her latest iteration is the scariest yet. Her Herald of Aggression Rhona is a powerful legendary archetype spell that can untap her whenever she casts her legendary spell.
Transforming Rhona costs a hefty 6 mana, but in return you get a new version of the Phyrexian Destructor. When Rona, Tolarian Obliterator takes damage, its source’s controller exiles a random card from hand and may put it into play if it’s a land, but otherwise it’s free to cast.
three Invasion of Arcavios // Founder’s Call
The second combat card on this list is Invasion of Arcavios. A very powerful spell-based siege that teaches spells and transforms to double everything you cast. When Avcavios’ Invasion enters the battlefield, you can teach an instant or sorcery from your library, graveyard, or out of game to find a card in your sideboard.
When all defense counters are removed, it transforms into an enchantment of the Founders. Any moment or sorcery you cast doubles with this enchantment, giving you all kinds of copies that can cause chaos.
2 Zingitaxias
The new Jin-Gitaxias has so much going on that it’s hard to keep it straight. First off, Jin-Gitaxias has ward 2 to keep safe, so of course it’s hard to deal with. Then, when you cast a noncreature spell with a mana value of 3 or greater, keep your hand full by allowing you to draw cards.
Sage When transformed into The Great Synthesis, the first chapter draws more cards. Second, you can return any non-Phrexian creature to its owner’s hand, even yours.
Then, when the final chapter comes, you can cast any number of spells from your hand for free and return The Great Synthesis to Jin-Gitaxias.
One Fairy Mastermind
Based on Magic World Champion Yuta Takahashi, Faerie Mastermind is a card drawing machine. The main ability to note is that you draw a card whenever your opponent draws a second card each turn.
You can put your Faerie Mastermind into play for just 2 mana. You can cast it in response to an opponent’s spell or ability to draw a second card and draw a card right next to it.
