Vengeful Apparition (Yellow) [MST156] (Part the Mistveil)

When this leaves the arena, if you control no Illusionist auras, you may play your next aura with cost 1 or less this turn as though it were an Instant. If you do, it enters the arena with a +1POWER counter. Ward 1 (If you would be dealt damage, destroy this to prevent 1 of that damage.)
