Activate this card by targeting 1 "@Ignister" monster you control. That monster gains 800 ATK, also all monsters your opponent controls must attack that monster you control, if able. If this face-up card in its owner's Spell & Trap Zone has left the field because of an opponent's effect, and is now in the GY or banished: Draw 1 card. You can only use this effect of "A.I. Shadow" once per turn.
