Finally defeated Mage Knight’s Solo Conquest
After 5 (ish) failures.
Right now my big insight is — don’t rush unless the dummy is getting obscenely lucky. My first few games had my racing through my deck, when I could have paused a turn or two to gain crystals, pillage or even just use my cards for their printed values instead of sideways.
And be wary about dropping reputation until you have 3+ followers.
Update — Managed another win, so I think it may not be a fluke (new high score — 157).
