Flying Revolt — When Airdrop Aeronauts enters the battlefield, if a permanent you controlled left the battlefield this turn, you gain 5 life.
Tokens that leave the battlefield will satisfy a revolt ability.
Revolt abilities check only whether a permanent you controlled left the battlefield this turn or not. They don’t apply multiple times if more than one permanent you controlled left the battlefield. They don’t check whether the permanent that left the battlefield is still in the zone it moved to.
All cards in the Aether Revolt set with triggered revolt abilities use an intervening “if” clause. A permanent you controlled must have left the battlefield earlier in the turn in order for these abilities to trigger; otherwise they do nothing. In other words, there’s no way to have the ability trigger if no permanent you controlled has left the battlefield that turn, even if you intend to have one do so in response to the triggered ability.
