Ezio Auditore da Firenze

Menace

Assassin spells you cast have freerunning {b}{b}.
(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 {w}{u}{b}{r}{g} if that player has 10
or less life. When you do, that player loses the
game.
