Acrobatic Cheerleader

Once Acrobatic Cheerleader's ability triggers, it won't trigger again as long as it remains on the battlefield, even if the triggered ability is countered or the flying counter is somehow removed. If an effect would cause Acrobatic Cheerleader's ability to trigger again, that part of the effect won't do anything.

Survival abilities (and other abilities that trigger at the beginning of your second main phase) will trigger at the beginning of the second main phase you take in a turn. They won't trigger during your third, fourth, or other additional main phases in a single turn, if effects somehow cause you to have more than two main phases.

If a creature's survival ability triggers but the creature leaves the battlefield before the ability resolves, use its tapped or untapped status as it last existed on the battlefield to determine whether or not the ability will do anything.
