I believe you want an Ironworks ASAP, to the point where I'd consider Ironworks/Swindler. Why? Because Hamlet/Library is a thing. You can buy up a bunch of cantrips, and just get a few Swindlers (+actions with Hamlet and Library draw) to feed your eventual 3-pile, I would think. But then again, thinning is hwinning, so Remake is probably good on first turn after all, especially since you are playing with ruins for Estates, which means free Hamlets later on.
You can buy Squires for +buy (and the coin), and to possibly trash into Swindlers for piling. This board seems kind of fun.
Is Possession a thing here? Seems worth investing in after you've cleaned up your deck, but Swindler might hit that Potion into a Rats. That would suck.
I see that Rats can be trashed by Remake into Libraries or Duchies later on, but that's pretty flamboyant and slow, so eh. I still will find a use for those blasted Rats yet!!!!!!!
