Hallow King

{r},{b}, or {g} creatures you control gain +1/+1.
When Hallow King attacks, choose one only once per turn:
{b}: Haunt (Creatures that defending opponent controls gain a -1/-1 counter.)
{r}: Hallow Fire (Creatures that die this turn are exiled instead being put into the graveyard.)
{g}: Corrode (Whenever an opponent takes damage this turn, you gain twice that much life)
