Pyra, Flame Nova Blade

When Pyra enters the battlefield or transforms
into Pyra, there is an extra combat after this
phase. Untap this card at the start of that combat.
When a creature you control deals combat
damage to a player, you may add {r} or {w} to your
mana pool. Until end of turn, you don't lose
this mana as steps and phases end.
