Lasko of the Flamefist

Lasko of the Flamefist can't be blocked by
creatures with power 3 or greater.
Whenever Lasko of the Flamefist deals combat
damage to a player, exile the top card of that
player's library. You gain life equal to that card's converted mana cost. Until end of turn, you may
cast that card and you may spend mana as though
it were mana of any color to cast it.
