Retribution of the Damned

Create two 0/2 White Spirit creature tokens with "When this creature is dealt combat damage, it deals that much damage to the creature which damaged it. That creature's controller loses 1 life.".
Until end of turn, Spirit creatures you control gain +1/+1, Vigilance and "When this creature dies, each opponent loses 1 life and you gain 1 life.".
Don't let the halo fool you.
