Simorgh Repulsion

Discard 1 Winged Beast monster; return all cards in your opponent's Spell & Trap Zones to the hand. You can banish this card from your GY; reveal 1 Winged Beast monster in your hand, and if you do, reduce the Levels of monsters in your hand with that name by 1 for the rest of this turn (even after they are Summoned). You can only activate 1 "Simorgh Repulsion" per turn.
