Tip to get the Challenge: Set your deck to Pro-You, for lack of a better term, cards only. Since the computer uses the same cards as you, the game becomes less about how much of a jerk you are and more about how you play your cards. The build I use is School, Wain, Fort, Babylon, Conjure Bricks, Conjure Crystals, Sorcerer, and Pixies (3 of each)
Hope this helps someone ^.^
Note for those having trouble with the boss, as I did: Carefully rocket past him and go past the green gates. The Super Blaster in there owns the thing.
Neat concept, but blatant copying of other games plus dissapointing delivery gives this a 2/5.
Also, the spike hitboxes on the monkey level are WAY too huge.
