Card Rules: Rulings powered by The Netrep API. If there is a Spell or Trap Card on your opponent's side of the field , 'Black Tyranno' cannot attack directly. If there is an Attack Position monster on your opponent's side of the field 'Black Tyranno' cannot attack directly. If your opponent has only Defense Position monsters on his side of the field 'Black Tyranno' can attack directly even if some are face-down. If an effect resolves during the Battle Step of 'Black Tyranno''s direct attack that results in a Spell Card Trap Card or Attack Position monster being on your opponent's side of the field a replay occurs. If your opponent's only monster is in face-up Defense Position but it is equipped with 'Ring of Magnetism' 'Black Tyranno' must attack that monster if 'Black Tyranno' attacks. [Re: Shadowslayer] For 'Shadowslayer' (unlike cards like 'Black Tyranno' and 'Drillago') only the Monster Card Zones are looked at. If all of your opponent's monsters are in Defense Position then 'Shadowslayer' can attack directly even if your opponent has Spell and Trap Cards on the field.
