Engine is always better
But seriously, with SP, Bandit Camp, Alch, and Monument, in addition to Remake for trashing, there could be a pretty fantastic engine here. You shouldn't worry about Bandit Camp clogging up an SP engine, especially if you've trashed out Coppers and Estates. SP will almost always draw more cards than Alch in this kind of engine.
With 3 starting Estates, you can Remake those up to Monuments for free. You're probably opening with a Silver and maybe picking up a Monument on the reshuffle. So I feel like gaining engine components to a satisfactory degree isn't a huge problem here. Obviously the big question is whether it can outrace Vault - I think it'll be close, but Vault still isn't super-amazing-fast to 8 Provinces.
