changeling monsters

You may have creatures you control assign their combat damage this turn as though they weren't blocked.

Each creature gets +1/+1 for each other creature on the battlefield that shares at least one creature type with it. (For example, if two Goblin Warriors and a Goblin Shaman are on the battlefield, each gets +2/+2.)

Changeling (This card is every creature type.) : Until end of turn, creatures you control have base power and toughness X/X and gain all creature types.
