Flying
Whenever Archon of Redemption or another creature with flying enters the battlefield under your control, you may gain life equal to that creature's power.

The creature’s power is determined as the triggered ability resolves, so it will take into account any effects that modify it. If the creature has left the battlefield by the time the triggered ability resolves, its last existence on the battlefield is checked to determine its power.
