Cloth, Protector of the Weak

Whenever Cloth, Protector of the Weak blocks a creature with power equal to or greater than her own, you may pay {g}{g}{g}{x}, where {x} is the creatures power - Cloths power. If you do so, return the blocked creature to its opponents hand and put 2 bravery counters on Cloth. If Cloth gains 10 bravery counters this way, put a +1/+1 counter onto each creature you control
