spellcaster decks yugioh this preconstructed deck offers 40 carefully chosen cards Spell Power Mastery - Structure

During either player's turn, when a card or effect is activated that would inflict damage to your opponent, while you have another "Performage" monster in your Graveyard: You can banish this card from your Graveyard

This costs 5 mana, plus 3 for the activation, but you can pretty easily go and find something from your deck

This is most effective if youve got some strong enter triggers out on the battlefield, but either way Id save this in your hand until you need it to dodge removal or a board wipe

Shes the sort of threat thats not too tricky to play around, but she is certainly going to be a question that needs answering if she does make the cut
