Deathtouch (Any amount of damage this deals to a creature is enough to destroy it.)
Whenever an Assassin you control deals combat damage to a player, draw a card.
Assemble a swarm of Assassins and use deathtouch and evasion to grind opponents down while drawing extra cards on every connection. Ezio turns each unblocked Assassin into card advantage, so you flood the board, attack widely, and convert that into a snowballing engine that eventually closes with combat or a payoff once your hand and board are stacked.
Tribal Assassins payoff that generates serious card advantage from many small attackers
Deathtouch makes Ezio and his crew brutal blockers and attackers, deterring big creatures
UB gives access to premium removal, recursion, and card draw to support the engine
Multiple unblocked attackers can each trigger draws, snowballing hard
Relatively shallow Assassin tribal pool compared to Zombies/Vampires
Relies on creatures connecting, so board wipes and fog effects shut it down
Five-mana commander that needs a board to do anything meaningful
Vulnerable to flyers and ground-stalling if it can't push damage through
Lets attackers connect for damage then dodge blocks, maximizing triggers safely.
Add unblockable enablers (Whispersilk Cloak, Rogue's Passage, Trailblazer's Boots) and anthems like Coat of Arms to maximize triggers and damage. Lean into UB's best interaction and recursion—counterspells, targeted removal, and reanimation—to protect the engine, and consider extra-combat effects to multiply draws. Tighten the curve and add fast mana to deploy Ezio and a follow-up board sooner.
