If <Yuji Itadori> is on your field, reduce this card's AP cost by 1 while in your hand. Choose up to one character with 5000 or less BP on your opponent's front line and sideline it. Then, if there are two or more characters with 4000 or more BP on your opponent's front line, choose up to one [Jujutsu Sorcerer] affinity card with 4000 or more BP on your field. It gains 2000 BP until the end of the turn.

[Special] Choose one character on your opponent's front line and sideline it.
