Ajani, Strength of the Pride

In a Two-Headed Giant game, Ajani's last ability exiles permanents as long as your team's life total is greater than your team's starting life total by 15 or more life.

Each creature with lifelink dealing combat damage causes a separate life-gaining event. For example, if two creatures you control with lifelink deal combat damage at the same time, Ajani's Pridemate's ability will trigger twice. However, if a single creature you control with lifelink deals combat damage to multiple creatures, players, and/or planeswalkers at the same time (perhaps because it has trample or was blocked by more than one creature), the ability will trigger only once.

If Ajani's Pridemate is dealt lethal damage at the same time that you gain life, it won't receive a counter from its ability in time to save it.

Whether you have at least 15 life more than your starting life total is determined as Ajani's last ability resolves.
