@harsh yarrow had the idea first, go celebrate their contributions.
Mac and Minor Circuit:
Mac-attack (Uncommon Joker). Gets a 0.1x Chips multiplier for each non-Overkill (fire-causing) hand that you play. Getting an Overkill hand will reduce it by 0.1x Chips mult instead.
Glass Jaw (Common Joker). Glass Cards give 3x Mult instead of 2x, but if any Glass Cards break, ALL other Glass Cards in your current hand break as well.
Blitzkrieg Rush (Uncommon Joker). On final hand of round, has a 1/6 chance to instantly win you the Blind no matter what. Otherwise, give +1 Chip.
Disco Fever (Uncommon Joker). Gains 0.2x Mult for every non-Straight/Flush-based hand that you play, resets after a hand is played with either a Flush or Straight.
Hippo Hunger (Rare Joker). Eats the rightmost Perishing/Food Joker to the right upon selecting a Blind, and will permanently copy its effect at HALF effectiveness. (50 Chips, 10 Mult, 7.5 Mult, 1.5x Mult, 1 in 2 chance to retrigger, etc).
