Let's cut to the chase
Thats made up of 10 unique cards all from A Goofy Movie in various quantities Improvements + Cards To Drop The easiest, most fun way of improving this deck would be to collect more of the characters from A Goofy Movie until you have four of each
Nicol Bolas, the Ravager / Nicol Bolas, the Arisen The thing thats most appealing about Nicol Bolas, the Ravager isnt that it's an overpriced Burglar Rat, but rather that it can transform from one of the best dragons in Magic into a planeswalker thats ready to take over the board if left unchecked
