Would this idea work better as an Event? This is not a card that you'd normally buy more than one copy of, anyway, as the Remake part is pretty weak.
But as it is, this card is essentially a weaker version of Rats--i.e. a card that turns junk into more expensive junk. Graverobbering Squires sounds nice, but normally, wouldn't I rather have a Gold or Lab out of the trash than a Squire?
I do like how it synergizes with itself, but it's weaker than any other TFB card at actually trashing-for-benefit (even if you include the pseudo-Expand effect.
For example, say you put the token on Copper. Ok, your Bishops get an extra VP when they trash copper, but you have to 1) have the Bishops collide with Copper, and 2) have not trashed Coppers earlier. Once you've cleared out your Coppers, you then have to have lots of copies of another card available, then buy another (fairly useless) Shady Dealer and then have your spam card again collide with your TFB's.
Ok, this combos great with Fortress and Rats, but not much better than TFB already combos with those cards.
