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.
