Reprinting decks and sets from Yu-Gi-Oh
Theres no right way to make a deck, but there is a helpful mindset: find out what you want to achieve, find cards in your collection that support that strategy, and then take your custom-built deck it into battle
(Equipment, Auras you control, and counters are modifications.) If the creature you control is an illegal target as Signature Slam tries to resolve but the creature you don't control is still a legal target, each modified creature you control (which may include the target creature you control if it's still on the battlefield) will still deal damage equal to its power to the creature you don't control
Watching them devolve into chaos over one card is a blast
