Millennium-Eyes Restrict
Card Text: “Relinquished” + 1 Effect Monster
Once per turn, when your opponent activates a monster effect (Quick Effect): You can target 1 Effect Monster your opponent controls or in their GY; equip that target to this card you control. This card gains ATK/DEF equal to that equipped monster’s. Monsters with that equipped monster’s name cannot attack, also their effects on the field and their activated effects are negated.
The Verdict
Case 1: Player-A activates Ash Blossom, Player-B responds by activating the negation effect of Millennium-Eyes Restrict: Ash Blossom’s activated effect is negated.
WINNER = Millennium-Eyes Restrict
Why: Ash Blossom‘s activation cost is to discard it into the graveyard, therefore Millennium-Eyes Restrict is able to target the discarded card, assuming it was successfully sent to the graveyard via discrd.
