Hellkite Charger

You decide whether to pay {5}{R}{R} as Hellkite Charger’s ability resolves.

Hellkite Charger’s ability may trigger multiple times in the same turn, since its own ability gives it multiple chances to attack. Each time it resolves, you may create an additional combat phase.

If you pay {5}{R}{R}, the new combat phase immediately follows the current combat phase. There is no main phase in between.
