i just managed to beat him. my deck had three trump cards, a few half cards, a pi card, and the chili pepper. i also had the card from the tarot lady that's 17 points but heals your hp. if you pick the heart set of cards, using the chili pepper to use the trump card will regain the hp you lost from the pepper as well as past hp you lost. i also had a few negative cards to counteract the tarot card so you'll still get the hp but it's less likely you'll bust. hope this helps! :)
