The gimmick

What Soul Fysh does

The one thing that defines this fight — read this before you draft your route.

A pattern fight: Soul Fysh dumps Beckon status cards into your deck (1 energy; if not exhausted or discarded by end of turn they hit you for unblockable damage) and periodically turns Intangible, reducing your hits to 1. Winning means cycling Beckons out and saving burst for the windows it is vulnerable.

Game plan

How to beat Soul Fysh

Ordered priorities for the fight. Tools shift by deck, but these beats hold across most archetypes.

  1. Learn the rotation: it telegraphs a repeating multi-turn pattern, so plan your big damage on the turns it is not Intangible.
  2. Have a plan for Beckon — discard or exhaust effects keep the unblockable chip damage off you; card draw that filters your hand is your friend.
  3. Do not waste your best attacks into the Intangible turn, where everything is shaved to 1 damage; bank and unload after it drops.
  4. Front-load mitigation against the chip damage so a string of Beckons plus its attacks does not quietly bleed you out.

Class-specific tips

How each kit leans into this matchup. Open a class hub for full builds and card priorities.

Silent builds →

Discard and draw-and-discard cards cycle Beckons out cleanly, and poison keeps stacking through Intangible turns.

Ironclad builds →

Exhaust effects scrub Beckons from your hand, and a single big-burst turn lined up off the Intangible window does serious work.
