شبح الخدع أو حلوى

If you control a "Ghostrick" Link Monster or Field Spell: Target 1 face-up monster your opponent controls; your opponent can pay 2000 LP to make this effect become "Set this card face-down instead of sending it to the GY", otherwise, this turn, that face-up monster cannot attack, its effects are negated, also it is changed to face-down Defense Position during the End Phase. You can only activate 1 "Ghostrick or Treat" per turn.
