A slight twist on Embiggen Druid is enough to get you over the line with this one: add two copies of Kobold Stickyfinger where you’d usually put the Dragonmaw Poachers on the ladder, sprinkle the mix with a few Acidic Swamp Oozes depending on your taste, and the raw stats on board plus the swing turns where you steal or destroy the weapons will put you over the top against the Kobold King.
