Sword of Godric Gryffindor

You may sacrifice a horcrux rather then pay
the mana cost of Sword of Godric Gryffindor.
Equip{0}: Equipped creature gets +3/+0 and first strike. When equipped creature deals combat
damage to a player, put a +1/+1 counter on it.
Only equip to a creature with Bravery.
''Maybe the sword of Godric Gryffindor could defeat
the Heir of Slytherin'' ''...Interesting theory. Has
anyone ever tried sticking a sword in Voldemort?
