Ezio Auditore da Firenze

The alternate win condition here is the tell: this is a commander built around a specific combat loop, not a stat line. Freerunning does the setup work, cutting the cost of your Assassin spells to two black once anything with the Assassin type (or your commander) has connected in combat. Menace on a 3/2 body is the enabler: hard to double-block, cheap to deploy, and precisely the kind of creature that reliably lands the first hit that turns freerunning on. Once that engine is running, every subsequent Assassin becomes a discount deployment, chaining bodies onto the board faster than the mana would normally allow.

Then the second ability reframes the whole plan. A five-color payment on combat damage that ends the game outright, gated behind an opponent sitting at ten life or less, is a design that asks a black-based deck to reach into all five colors for a finisher it will fire exactly once. The tension is deliberate: black wants to attrition an opponent low, but the kill button demands a rainbow of mana the deck's core color does not produce on its own. It is a card that wants two decks stapled together, the mono-black Assassin swarm that generates the damage and the five-color base that pays for the execution. Freerunning builds the pressure; the clause is the reward for solving the fixing problem underneath it.
