So would I. HSReplay doesn’t save Puzzle Labs, I only screenshotted the end state which was right at the moment 35 stacks of fatigue were being added to the history bar, and now I’m on the unwinnable Full Northshire puzzle and can’t go back to experiment.
From what I can reconstruct and recall, the solution was: Archer a minion, Lesser Heal it to draw the Pyro (7 mana left). Play the Pyromancer, and play Recruiter on Cleric (3 mana). Power Word: Shield (now free thanks to the nerf) on enemy Northshire will cause your Pyro to kill your Archer, leaving 4 damaged minions on your board. Play Fungal Enchanter with the last of your mana, get 4 draws from your Northshire. The 1 fatigue is survived by the heal from Fungal. Now you have the Clerics, and Boom has drawn 5 times. Battery Pack to refill mana (Recruiter and Pyro now have 1 health, 3 other damaged minions in play). Play two Clerics and Binding Heal one of them. It has full health so no fatigue, but the Pyromancer explodes again, killing itself and the Recruiter (and not the enemy Cleric since we buffed it earlier).
You now have 3 damaged Clerics, a damaged Fungal Enchanter, a damaged Sylvanas, 7 mana and Boom has one damaged Cleric. Play the last Cleric, perform The Swap, Treachery Boom’s Cleric back to him, then Circle. That’ll heal 6 minions and trigger 5 Clerics for a total of 35 stacks of fatigue, including the ones from before.
