Gunk Up

Deal 4 damage 3 times. Add a Slimed into your Discard Pile.

Gunk Up is a common Defect attack costing 1 Energy that deals 4 damage 3 times and adds a Slimed status card into your Discard Pile. The multi-hit nature makes it effective against enemies with small amounts of Block, and the total 12 damage output is strong for a common card despite the Slimed drawback.

Gunk Up's status generation synergizes powerfully with Smokestack, which deals 5 damage to ALL enemies whenever a Status is created, and with Iteration, which draws 2 cards the first time you draw a Status each turn. Compact transforms Status cards in hand into Fuel, and Rocket Punch has its cost reduced to 0 when a Status is created.

As a Defect card, Gunk Up fits into Status-synergy builds that turn the Slimed drawback into an advantage. Against bosses like Soul Fysh and Ceremonial Beast, the multi-hit combined with Smokestack triggers deals substantial total damage. Pair it with other Status-generating cards like Boost Away and TURBO for a deck that weaponizes its own downsides. Avoid picking Gunk Up without Status synergies, as the Slimed cards bloat your deck.
