Ok, first, you should do all your side quests, and level up a few times. By the way, as you keep playing you just get more strategic. Then go to the Bazaar and get the biggest deck you can find. (Sell your old one.) Then go try again at stupid Meowiarty.
(Oh and KI, I LOVE how you based each world on a different scenario. Sherlock Bones, Meowiarty, Krokopatra. LOVE IT!!!)
See you in the Sprial! Cheyenne GriffinCaller Level 51, Myth.
