Ib Halfheart, Chargecaller

Other Goblins you control have Battle cry.
At the beginning of your end step, sacrifice each other Goblins that attacked this turn. Ib Halfheart, Chargecaller deals X damage to each opponent, where X is the number of Goblins sacrificed this way. Then, create a 1/1 red Goblin creature token.
''All you other guys, CHARGE!!! Wait, don't forget the boom-booms!''
