A go at the alternative to BM/Q for the sake of comparison, unoptimal for now:
Open TR-Bridge via Baker.
Shuffle.
Draw TR, Bridge C, C, Hovel. Double Bridge, pick up two TRs, Bridge and Smithy via double Stonemason.
Draw CCCCOgie...buy Smithy?
Draw Necro, C,
Shuffle
TR, TR, Smithy. Play Necro, TR the TR into a Smithy to draw TR, Bridge Bridge, 3 coppers. Use the TRd TR on your other TR to double your Bridges. Play Smithy drawing Hovel, Copper, Stonemason. Now you have 8 money, 5 buys, and 2 Coppers and a SM left in your draw (not good...) with everything costing 4 less. Buy 4 Princes via Stonemason and flat-purchase two more TRs and a Smithy (can't overpay 0, but maybe Highway comes into play here). Draw C, C, SM
Shuffle
Necro, Smithy.
This is now turn 6.
Play Necro, Smithy, draw TR, Prince, Ogie. Prince the TR.
Draw TR, TR, Smithy, Bridge, Bridge. TR TR from Prince into Smithy, draw 2 Princes, 3 copper and your last TR.TR TR into double Bridge, Princing a Prince. [I'm missing an action here...]
Overpay for Doctor by 7, discarding or trashing all but 7 remaining cards (Lots of SMs and X), not seeing the other Prince.
Draw dead for a turn or two?
Draw Prince at the bottom of your deck into the kickoff hand of Prince-TR-Bridge-Bridge-X or a variant with Smithy to draw.
Maybe Chancellor or Scavenger have a place at some point instead of a Smithy?
