I really like Miser, and I agree it's underrated, but I can't help but wonder: wouldn't Coppersmith be better here? You're gonna draw your deck with impunity even without trashing, since you'll have massive draw with Wharf and Pathfinding, and plenty of Villages. Coppersmith effectively gives +$7, just like Miser, but you don't have to play a Coppersmith 7 times first and can spend your early turns buying and maybe Duplicating Wharves and Farming Villages.
