Akali, Blade in the Shadows

Haste

Akali cannot be blocked.

The first time a creature deals combat damage to an opponent each turn, Surveil 1 then draw a card. If
that creature was Akali, look at the top card of your library. if it's an instant or sorcery spell, you may
cast it without paying its mana cost until your next
turn. Otherwise, put it into your hand.
