When a monster, except a Spellcaster-Type monster, is Normal or Special Summoned to your opponent's side of the field while you control another Spell Card and your opponent controls no Spell Cards (except during the Damage Step): That monster cannot attack or activate its effects this turn. If you do not control a Spellcaster-Type monster, destroy this card.
