Ultimate Brainwave Deck is the answer to your magic prayers—if your prayers involve making your mates question their sanity.
The effect? Absolutely bonkers: A spectator names any card, and lo and behold, its back colour is different from the rest of the deck! It’s direct, it’s clean, and it’s exactly what it says on the tin (no dodgy labels here). Just watch their jaws drop while you bask in the glory of your magical genius. Enjoy the bewilderment!
