Lautrec, the Embraced

Menace, Trample
Whenever a creature you control deals combat
damage to a player, exile that many cards form
the top of that players Library, then choose one
and put a Embrace counter on it.
You may cast spells and play lands from among
exiled cards with Embrace counters on them, and
you may spend mana as though it were mana of
any color to do so.
