Burning Forest

Burning Forest enters the battlefield with three perish counters on it.
{t}: Add {r} or {g} to your mana pool, then remove
a perish counter from Burning Forest. If you
can't, add {c} to your mana pool instead.
"It's a shame we had to burn the Sacred Forest. However, that's one less place for the Iryo to hide."
