Whenever a non-Human creature you control attacks, look at the top six cards of your library. You may put a Human creature card from among them onto the battlefield tapped and attacking. It gains indestructible until end of turn. Put the rest of the cards on the bottom of your library in a random order.
Flood the board with cheap non-Human creatures (especially tokens), swing wide, and use each non-Human attacker's trigger to dig six cards deep and drop powerful Humans onto the battlefield tapped and attacking for free. Snowball value-laden Humans like Angrath's Marauders, Combat Celebrant, and Kiki-Jiki into either a lethal alpha strike or a hard combo kill, usually as early as turn 4-6.
Generates explosive free mana value—triggers cheat in Humans worth far more than you paid
Goes wide quickly and punishes opponents who can't sweep early
Access to strong combo finishes (Kiki-Jiki, Combat Celebrant) for fast kills
Aggressive Boros plan that pressures the table from the start
Extremely commander-dependent; the deck stalls hard without Winota online
Vulnerable to board wipes and targeted removal on the commander
Needs a critical density of both non-Human tokens and Humans to function
Limited card advantage and recovery in mono Boros if the swarm is answered
