Traditionally filled with flyers, counter spells, and massive leviathans, blue cards in Magic: The Gathering counts themselves among some of the strongest 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 top blue cards have convoke, a mechanic that is traditionally found on white and green cards, letting you tap your creatures to pay for part of or even all the spell’s mana cost. Among the best blue cards are several cards that transform, some can draw you tons of cards, and others that help control the board.

10 Ephara's Dispersal

Ephara's Dispersal by Awanoi (Angela Wang)

A versatile tempo spell, Ephara’s Dispersal can be tech to keep your opponent's best attacker off the board or to remove a creature giving you problems from the board for a turn or two. Even better, Ephara’s Disperal gets cheaper if you target an attacking creature, reducing the mana cost by two generic mana.

As a one-mana bounce spell that also surveils 2, Ephera’s Disperal is an incredibly high-value spell, filling your graveyard with spells you can bring back and shifting through cards you don’t need from your deck.

9 Zephyr Singer

Zephyr Singer by Lie Setiawan

A strange creature that breaks traditional color trends, Zephyr Singer is a blue creature with convoke, letting you tap creatures to help pay for the mana cost. Each creature you tap to cast Zephyr Singer gains a flying counter. On your next turn, you suddenly have an army of flying creatures to attack alongside the Singer.

The flying ability is found all over blue cards, but vigilance is relatively rare, though not unheard of. You’ll need a creature-heavy deck to capitalize on Zephyr Singer, but it could also work well with cards that create tokens too.

8 Transcendent Message

Transcendent Message by Liiga Smilshkalne

Another blue convoke spell but this time your creatures can help you draw tons of cards off of this Instant spell. Transcendent Message costs a staggering four blue mana and then X.

Your creatures can be tapped to pay for both the X and the blue mana costs, so long as the creatures you tap for the blue mana are blue themselves.

Transcendent Message will likely see play in Commander more than other formats, being able to draw a ton of cards even when all your lands are tapped is very strong. There are tons of potential to use your creatures to draw cards before a board wipe resolves or in response to blocking an incoming attack where you might lose a bunch of creatures in combat.

7 Complete The Circuit

Complete The Circuit by Eelis Kyttanen

Another convoke spell, which is good since spending six mana on this instant can be a little mana intensive for most decks. Complete the Circuit lets you cast sorcery spells as if they have flash, allowing you cast them at instant speed.

Then, you get to copy the next spell you cast two times, giving you a total of three spells on the stack and letting you pick new targets for the copies. There are tons of possibilities to explore with Complete the Circuit since giving sorcery spells flash changes how they interact with the game.

6 Invasion Of Segovia // Caetus, Sea Tyrant Of Segovia

Invasion of Segovia by Edgar Sanchez Hidalgo

The first of the blue battle cards among the top blue cards from March of the Machine, the Invasion of Segovia is a goofy card that has a powerful effect when it transforms. As it enters the battlefield you get two 1/1 Kraken tokens with trample, which might only do a little on their own but have the potential to do great things.

Once transformed into the creature Caetus, Sea Tyrant of Segovia, a massive (for Segovia) 3/3 Leviathan that gives all your noncreatures spells convoke. Caetus also helps you cast those non-creature spells by untapping four creatures of your choice on your end step, giving you an opportunity to cast instant speed spells with your creatures or even recovering your board after tapping out.

5 Chrome Host Seedshark

Chrome Host Seedshark by Donato Giancola

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. You add +1/+1 counters to your Incubator token equal to the spell’s mana value.

The Seedshark is a Phyrexian version of the Shark Typhoon enchantment from Ikoria: Lair of Behemoths. Mechanically, the Seedshark does very similar things for less mana, though the tokens you create have a mana commitment before you can start attacking with them.

4 Rona, Herald of Invasion // Rona, Tolarian Obliterator

Rona, Herald of Invasion by Victor Adame Minguez

Rona has had a few cards printed since her introduction back in the Dominaria set but the latest iteration of her is the most terrifying yet. Rona, Herald of Invasion is a strong legendary archetype spell, letting you untap her every time you cast a legendary spell.

Transforming Rona costs a hefty six mana but in exchange, you get a new version of a Phyrexian Obliterator. When Rona, Tolarian Obliterator takes damage, that source’s controller exiles a card randomly from their hand, and if it's a land, you can put it into play, but if it's anything else you get to cast it for free.

3 Invasion Of Arcavios // Invocation Of The Founders

Invasion of Arcavios by Dmitry Burmak

The second battle card on this list is Invasion of Arcavios, a very strong spell-based Siege that tutors for spells and doubles up everything you cast once it transforms. When Invasion of Avcavios enters the battlefield, you get to tutor up an instant or sorcery from either your library, graveyard, or from outside the game, letting you find a card from your sideboard.

Once you get rid of all its defense counters it transforms into the enchantment Invocation of the Founders. Every instant or sorcery you cast gets doubled with this enchantment in play, giving you all sorts of copies to create chaos with.

2 Jin-Gitaxias

Jin-Gitaxias by Ekaterina Burmak

There is so much going on with the new Jin-Gitaxias that it is hard to keep it straight. First up, Jin-Gitaxias is naturally difficult to deal with since it has ward 2 to keep it safe. Then, it keeps your hand full by letting you draw cards when you cast any non-creature spell with a mana value of three or more.

Once transformed into the sage The Great Synthesis, you draw even more cards for the first chapter. The second time around, you get to bounce all non-Phyrexian creatures back to their owner’s hand, even your own.

Then, once the final chapter comes around, you can cast any number of spells from your hand for free and return The Great Synthesis to Jin-Gitaxias.

1 Faerie Mastermind

Faerie Mastermind by Joshua Raphael

Based on Magic World Champion Yuta Takahashi, Faerie Mastermind is a card drawing machine. The main ability you’ll want to pay attention to is whenever your opponent draws their second card each turn, you draw a card.

You can flash Faerie Mastermind into play for just two mana, letting you cast it in response to your opponent’s spell or ability that lets them draw a second card, and drawing you a card right alongside them.
