Honestly, I feel Invisible Deck is a much better buy than Brainwave. The two effects are similar,
and although Brainwave adds the color change, that extra punch puts much more heat on the effect
than Invisible does (which leads to much more unwanted questioning/skepticism by the spectators). I
feel Brainwave is a good effect, but Invisible Deck is much, much better. B_Magic score: C-
