Pokmon cards value is determined by three core factors: rarity (how limited the print run is), condition (physical state from Mint to Damaged), and demand (collector and competitive player interest)
Mickey Mouse, Wayward Sorcerer, meanwhile, is a solid card by itself thanks to balanced strength, willpower and lore stats, but becomes even more useful when used together with the Magic Broom, Bucket Brigade cards found in the Amber and Amethyst deck, as they will cost one fewer ink to bring out and then return to your hand (instead of the discard pile) when banished while Mickey is on the field
#9: Prophetic Prism Youre probably saying: This card sometimes doesnt even make my Sealed deck! I think thats a mistake most of the time, because card draw, mana fixing, synergy, and an artifact to use for many purposes in some decks has shown to be pretty important
Forced sacrifice on an attack trigger
The current inventory on TCGPlayer is definitely high at over 200 available though so its not like its super rare by any means
Owlin Historian This Limited card doesn't even get a permanent power boost from gravebreak in the form of counters
