Graxis, Esper Agent

Haste, vigilance, deathtouch
Graxis enters the battlefield with X +1/+1
counters on it.
Whenever Graxis deals combat damage to a
player, that player removes the top X cards from
his or her library from the game, where X is the
amount of damage dealt this way. You may cast
one nonland card of each type this way from
those cards, and spend mana as though it were
mana of any color to cast those spells.
