How star fusion works
2 copies at the same ★ merge into 1 copy at the next ★. 4★ only exists in Rumble Chess. In regular Co-op, your partner's Minions get a blue star and don't merge with yours.How it works
- Attack target: the enemy with the most HP (not the closest one).
- Who it affects: one random Minion.

Works well with
Pairs the community and I find good together. The notes come from my own research and player guides (written in English).
Jack-o'-Licks also costs the Commander's max HP on deploy, and the guide names Greenkeeper as the heal that sustains this kind of card.
Boom Shroom costs your own Commander HP on every attack and "needs healing", Greenkeeper heals the Commander every Ready.
Headless Jack's own note names "possibly Greenkeeper for survival", the guide's own hedge, not a certainty.
Named by the site owner and checked against the official text: this card gives ATK to Ninja Mango (or helps find it in the Shop), and Ninja Mango multiplies that ATK by the attack speed it gains per unique Minion.
What the community says
DBarely usable in PvP today
Gives ATK and heals the Commander, good only very early. In the late game it barely matters.

Variants
A base card and its Variants (I, II, III) can't be in the same deck. Variants inherit the base card's level. Get them in the Variant Recruit with Sprout Coins.
