Darkness Reincarnation (Full Art) (CST-062 N) [Clash of the Star Trees]

Play this card only if you control a J/ruler named "Stein, Deathly Star". Your opponent discards a card. Put the top two cards of your opponent's deck into their graveyard. If one or more resonators were put into their graveyard this way, you may put a resonator from among them from their graveyard into the field under your control.
