Defender, flying
Whenever Flumph is dealt damage, you and target opponent each draw a card.
Flumph's ability only triggers once each time it is dealt damage, even if multiple sources are dealing damage to it at once.
Flumph's ability will trigger even if it is dealt lethal damage.
Flumph's triggered ability is not optional. You must target an opponent if able.
If the opponent is somehow an illegal target for Flumph's ability when it tries to resolve, neither player will draw a card.
