For the reply to the fan letter, I'll attach a heartfelt charm.
Play this if you have a vanguard with "Luticia" in its card name! Choose a card from your soul, put it into your hand, and put this card into hand. If your soul has two or more Cursed Play cards, choose a card from your drop, put it into soul, choose one of your units, and it gets [Power]+5000 until end of turn.
