Allene, the Unbeatable

As long as you don’t control any Human spells and Allene, the Unbeatable is on the battlefield, all Squirrel Creatures you control get +1/1.

When a target opponent creature is defeated in a combat phase that Allene participated in, she gains +X/0 until after the next time she participates in combat, where X equals the Power of the target creature.
