Princeling + Prof. Nutter, Adventure Hard (JitteryKennon)

Princeling moves its own ★ up and down on Ready (below 2★ it gains +1★; at 2★ or more it drops back to 1★), and every time it goes up it counts as a promotion and gives Prof. Nutter Research. Muscle Melon is a must against Adventure Bosses, and Lady Tulip gets very strong in that mode. Grape Gatsby buffs the Shop. Coco Coinhog is your economy: only sell it on the last round.

• Princeling: Main piece (★): the plan revolves around it. Works together with: Prof. Nutter. Community tier list, April video (B): Goes up and down a star by itself every Ready, feeding promotions to the Kraut and Sister Cherry deck. A support, not the finisher. At level 10 it triggers Bombercarrot.
• Turnipette: Community tier list, April video (B): Comfortable early game: gains ATK by itself every Ready. Doesn't carry the late game against Tomato Twister, Orange Bros or Headless Jack.
• Coco Coinhog: Community tier list, April video (B): Solid B: stores Sun to sell later and turn into damage at once (with Lady Tulip, Eggydjinn and Acorn Outlaw). Also seen in Orange Bros decks.
• Prof. Nutter: Main piece (★): the plan revolves around it. Works together with: Princeling. Tier list (B, the wiki's rating): Collects Research on every promotion of another Minion and, on Ready, spreads double that as Temp ATK among the Minions in its column. A Promotion deck piece (with Princeling and Dr. Kraut); outside it, it does almost nothing. TreyEx puts it in S; here it's B, like the other pieces that only work in one deck.
• Shroomurai: Main piece (★): the plan revolves around it. Community tier list, April video (C): Huge pressure in rounds 1 to 3 and breaks shields on entry, but has no deck of its own and fades later.
• Grape Gatsby: Community tier list, April video (D): Gives ATK to Shop Minions on buy; it rarely pays off today.
• Lady Tulip: Community tier list, April video (B): Win condition of the spend-Sun deck, with pressure in rounds 7 to 9. Without the Variant the buff is huge but temporary; with it, smaller and permanent. Swings a lot with the weekly Blessing.
• Muscle Melon: Community tier list, April video (B): Its power is the Variant, which makes it gain ATK. A in a good Blessing week, B otherwise.
• Tomato Twister: Main piece (★): the plan revolves around it. Core piece of the plan: Tomato Twister (grows with every kill). Community tier list, April video (S): Gains ATK for every enemy defeated and snowballs fast; the opponent can't do much about it. Fits almost every deck (except Orange Bros). The strongest single card in the game.
