Scorchwing Seraph

Flying, haste
When Scorchwing Seraph enters the battlefield,
exile another target creature. Return that card to
the battlefield under its owner's control at the beginning of the next end step.
Whenever Scorchwing Seraph attacks, if players
own four or more cards in exile, create a 1/1
white Cleric creature token that's tapped and attacking. It gains flying until end of turn.
