Sword of Might and Magic

Equipped creature gets +2/+2 and has protection
from red and from green.
Whenever equipped creature deals combat
damage to a player, put a +1/+1 counter on target
creature you control, then exile the top X card of
your library, where X is the number of +1/+1
counters on that creature. Until end of turn, you
may play those cards.
