Glint of Insight (MP01-153 N) [Masterpiece "Pilgrim-Memories"]

Name a card. Your opponent reveals their hand and discards all cards that share a name with the named card. Remove two mystery counters from a J/ruler you control: This card in your graveyard gains [Remnant] until end of turn. Play this ability only if this card is in your graveyard. (You may play this card from your graveyard. If you do, remove it from the game instead of putting it anywhere else any time it would leave the chase.)
