Dawnbringer

Flying, vigilance, lifelink, double strike
Whenever Dawnbringer attacks, double the toughness of all attacking creatures until end of turn and all attacking creatures you control gain double strike until end of turn. Each turn, if you gained 8 or more life, create a flying 4/4 angel with vigilance and lifelink.
