Proven synergies
A different question from the grid above: not who Eidolon is listed with, but whose kit the skill text says Eidolon actually feeds — or feeds on. Each claim names the effect and, wherever the card records one, the skill producing it, so you can check it against the cards further down. Some of these pairs share no ranked lineup at all; each one says why.

B Eidolon · Ashen Verdict · Spectral Reaper developer pick Mid progression Beats 0 of 8 reference lineups 56.94/100 out of 100 Eidolon (X07), Ashen Verdict (X05) and Spectral Reaper (X03) score 56.94 out of 100 together, and each of the three has a job.
Eidolon is the multiplier, raising what the other two put out rather than adding a number of its own: carries 140% of damage amplification across its kit, and takes the front on purpose: this kit feeds on being attacked, and the front is where the attacks are. Ashen Verdict is the lock: every squad silenced or suppressed is a turn the enemy plan does not happen — Righteous Fervor applies Disarm on a 35% roll, and sits in the middle, where the support reaches both the front and the back. Spectral Reaper is the win condition, bringing 42% of the lineup's expected damage: Tamashi-kusari puts 742% into one enemy squad on a 35% roll, and stays in the back, out of the enemy's easy reach, and those range-4 skills lose nothing for it. The lineup works because Ashen Verdict’s Righteous Fervor applies Disarm and takes a squad out of the fight, so Spectral Reaper swings into a line that cannot answer; Spectral Reaper shuts off enemy recovery, so what Spectral Reaper deals stays dealt; Eidolon raises Spectral Reaper’s output directly rather than adding a number of its own. What you give up: no hero here feeds another one's trigger; no one hero clearly carries, so the damage is easier to interrupt. Budget note: every hero in this lineup can be completed without spending. This is one of the lineups recommended in-game by the developers -- the score above is what that classic core is still worth against the current roster.
