Krark, the Thumbless
Legendary Creature — Goblin Wizard
Whenever you cast an instant or sorcery spell, flip a coin. If you lose the flip, return that spell to its owner's hand. If you win the flip, copy that spell, and you may choose new targets for the copy.

Krark, the Thumbless doubles your instants and sorceries on a coin flip while returning them to hand on a loss — the floor is card advantage and the ceiling is cascading spell copies. It's a two-mana goblin that warps entire archetypes around it, and Rograkh, Son of Rohgahh pairs with it as a free zero-mana partner that lets the engine come down turn one. Okaun, Eye of Chaos // Zndrsplt, Eye of Wisdom completes the classic triumvirate: more flips means more triggers, and the ceiling gets absurd fast.
Best Commanders
Commanders with the highest synergy
Okaun, Eye of Chaos // Zndrsplt, Eye of Wisdom
Okaun, Eye of Chaos // Zndrsplt, Eye of Wisdom and Krark, the Thumbless are purpose-built for each other — every spell Krark copies is another flip trigger, and Zndrsplt draws a card for each one while Okaun doubles in power. The inclusion rate above 80% is the highest of any pairing for a reason.
Yusri, Fortune's Flame
Yusri, Fortune's Flame flips coins on combat damage, and Krark, the Thumbless stacks on top by flipping again for every spell cast — more flip events means Yusri's "five heads" payoff becomes realistically achievable in a single turn. The two cards reward the same behavior and share the same busted high-end.
Veyran, Voice of Duality
Veyran, Voice of Duality triggers off magecraft, and a copied spell from Krark, the Thumbless counts as an additional cast — so each spell with Krark on board is two magecraft triggers instead of one. Veyran's inclusion rate is lower because the deck is less coin-flip-themed, but the raw spell-multiplication synergy is real.
Urabrask
Urabrask taxes opponents for casting spells and rewards you for doing the same, and Krark, the Thumbless makes every spell you cast potentially happen twice. Each copied spell represents a free extra impulse draw from Urabrask's ability, turning Krark's variance into a card-flow engine.
The Howling Abomination
The Howling Abomination cares about instants and sorceries cast from anywhere but hand, and Krark, the Thumbless returning spells to hand on a loss sets up exactly that loop — cast, return, recast from hand, but the copies count as additional spell events. It's a synergy that rewards leaning into Krark's worst-case outcome.

Commander is the home format for Krark, the Thumbless — the longer game gives you time to set up spell-doubling loops, and the singleton rule means the coin-flip variance smooths out less than in a 60-card deck. In Legacy and Vintage, the card is technically legal but sees no meaningful play; two-mana creatures that rely on casting spells to generate value don't compete with the raw power and speed of those formats. Oathbreaker is the one non-Commander 100-card format where Krark could plausibly appear, since spell-heavy builds with a low-CMC signature spell can exploit the flip mechanic repeatedly. Outside those, Krark is a Commander card through and through.
