Menace
Assassin spells you cast have freerunning BB. (You may cast a spell for its freerunning cost if you dealt combat damage to a player this turn with an Assassin or commander.)
Whenever Ezio deals combat damage to a player, you may pay WUBRG if that player has 10 or less life. When you do, that player loses the game.
