Dust regular copy now (full refund for being nerfed) +1600
Craft golden: – 3200
HOF Rotation compensation for golden: +3200
Disenchant golden after rotation: +1600
Profit: 3200 dust

If you wait until rotation with regular copy (instead of dusting now) you will get 1600 for hof compensation and another 400 if you disenchant after, so net profit of 2000 dust

Dust it now, craft golden before rotation for extra 1600 dust (assuming you dust golden copy after roatation)

Secret passage looks like a good fit for quest rogue – If you have non-class cards in hand, at the end of turn when they go back to hand they’ll count again for quest progression. Also if you get it early you can dig for other-class generation cards.

It’s there mainly to activate apothecary on T4, faceless synergy is just a bonus.

Tony!
