[On Play] Add up to 1 red Character card other than [Uta] with a cost of 3 or less from your trash to your hand
Once youve got something powerful on the top of the deck, cheat it out with that tap ability
If a creature type is new and/or relatively undersupported, but you want to design a card that supports that type
If you want to go really deep, you can even try to put two things into play each turn with the backside of Esika, God of the Tree, Prismatic Bridge
Falling under the Amethyst ink type, this card has a very high cost of 8 ink to be summoned, however, if a player has an Elsa card already in play, the Spirit of Winter card can be "Shifted" and summoned for only 6 ink
Not all rare cards are expensive
