Creatures your opponents control with power 3
or lower can't block.
{2}{u/b}{u/b} - Target creature gains "When this
creature deals combat damage to a player, exile
cards from the top of that players library equal
to the damage dealt. You may cast spells from
the cards exiled this way and spend mana as
though it was mana of any color to cast them."

still mine." Demetrius
