Imposter Shift

When a monster effect that was activated on your opponent's field by targeting a card(s) on the field resolves, if any of those targets are in a different column than that opponent's monster, they can banish 1 card from their GY. If they did not, negate the activated effect. You can banish 1 monster from your GY; Special Summon 1 "Imposter Token" (Psychic/EARTH/ATK 800/DEF 800) with the same Level as that monster. You can only use this effect of "Imposter Shift" once per turn
