Card Rules: Rulings powered by The Netrep API. If you control 'Ultimate Obedient Fiend' and have no hand and no other monsters , but you have Spell or Trap Cards on the field 'Ultimate Obedient Fiend' cannot attack. [Re: Amazoness Archers] Monsters that have already attacked cannot attack again. If 'The Dark Door' is active your opponent still can only attack with 1 monster. Monsters which cannot attack still cannot attack (Toon Monsters the turn they are Summoned 'Ultimate Obedient Fiend' under the wrong conditions etc.) If 'Diffusion Wave-Motion' is in effect only the monster affected by 'Diffusion Wave-Motion' can attack. The ATK reduction of 'Amazoness Archers' is still applied in these cases where monsters cannot attack. [Re: Skill Drain] Restrictions are also lifted so you can attack with 'Ultimate Obedient Fiend' even if you have other cards on your side of the field.
