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 speed: +4%/8%/16% (1★/2★/3★), this round only.

Works well with
Pairs the community and I find good together. The notes come from my own research and player guides (written in English).
Valkyris compares TOTAL ATK (raw sum, ignores attack speed); with Bardcore Onion speeding everyone up, your team falls "behind" in that sum while dealing the same real damage, which is what triggers her bonus.
Tree of Light gains +1 Mana on every attack from ANY other Minion, and Bardcore Onion speeds up the attack rate of ALL Minions, meaning the team attacks more often per second, filling the Tree's Mana bar faster and making it fire more frequently.
What the community says
AVery strong
Attack speed for every Minion. In almost every deck with more than one attacker (Tomato Twister, Headless Jack, Chomper): by usage, the most important support in A.

Builds using this card
Legendary Scaling (Estrela)
Azure Astrologer and Tomato Twister keep growing into the late game. You need both Legendaries early.
Depressão (NoControlTower)
Summon rush from the NoControlTower channel: three Hogsteen on wave 1 flood the rival's side, Shroomurai clears yours and Tomato Twister grows with every kill. Closes before R9.
Frozen Guaca Sage + Tomato Twister (JitteryKennon)
A slower deck. Azure Astrologer buffs a frozen Guaca Sage in the Shop every round, and Tomato Twister deals the damage with Berrinetta's help.
Club Race 1/3: Conqueror's Temple (no duplicates)
Deck 1 of a set of 3 for the Club Race. Each phase needs its own deck with no Minion repeated between them, and these three share none. This one is for the Conqueror's Temple and is built around Shamaness.
