Whenever Raph & Mikey attack, reveal cards from the top of your library until you reveal a creature card. Put that card onto the battlefield tapped and attacking and the rest on the bottom of your library in a random order.
Drop Raph & Mikey, swing in, and cheat creatures straight onto the battlefield tapped and attacking every combat. You're a hasty beatdown deck that turns each attack into free, untaxed value, ideally hitting fatties or attack-trigger creatures to snowball damage and close fast.
Commander has built-in haste and trample, so it threatens immediately and isn't easily chump-blocked
Free creature into play attacking each turn ignores mana costs entirely, letting you cheat huge bodies
Gruul ramp lets you recast a 7-drop commander after removal without missing much tempo
Stacks brilliantly with extra-combat effects to multiply the cheated-creature trigger
Whiffs or hits a tiny creature if your library isn't dense with impactful creatures
The cheated creature enters tapped, so it can be killed before it ever blocks and offers no defense
Heavy reliance on the commander; if it's removed repeatedly the engine stalls
Color identity lacks strong interaction, card draw, and a way to protect the board from sweepers
Random bottoming means no library control or card selection from the trigger
A 15/15 trampler you'd never hardcast, perfect to slam in attacking for free.
Increase the density and average impact of your creatures so the trigger never whiffs—run mostly five-plus drops and creatures with ETB or attack triggers. Add extra-combat enablers (Aggravated Assault, Moraug, Aurelia-style effects) and haste/anthem support like Xenagos and Fervor to maximize each swing. Round out with Gruul ramp (Cultivate, mana dorks, rocks) to land the commander early and recast it through removal.
