Ive been looking for ways to put some of our Magic cards to other uses, and so far Ive come up with seven different crafts to use up extra Magic cards and tokens
It can get back one of our synergistic spells, one of our win conditions, or just a piece of interaction we know well need, while still being a great board wipe
"Trishula, Dragon of the Ice Barrier", "The Phantom Knights of Break Sword", and "PSY-Framelord Omega" from Battles of Legend: Light's Revenge
Learning - It will happen some time that all 4 copies of the card you need are in the bottom 15 of a deck, larger decks can help simulate this and help a person learn how to come at problems in other ways when their deck doesn't cooperate
