Not sure if this card is elegant, will work with it more later
But heres a different sort of scrap: It's probably harder to get off then scrap, but it should synergies well with imp and Conclave: since it trashes non duration cards you have in play, you could deliberately trash some cards to enable Imps abilities better. Or you could play an imp, draw into Analyst, and use analyst to trash the imp if your desperate.
Unless you have Ruins in the game, or ways to play coppers or silver, its not a good traditional trasher.

Analyst
$4 - Action
+1 Action
You may trash a Non-Duration card you have in play. Choose a different thing per $2 it costs (round down): Gain an imp; Gain an horse; Gain a card costing $1 less then it; +2 Coffers; +2 Cards
This looks fun, but some suggestions:
- I think 4 options are sufficient here. The only way to trigger all five would be by trashing a Colony, and Colonies don't end up in play. Which one to cut? Probably the +2 Cards, as Analyst already gives multiple ways to add draw to your deck.
- The Horse gaining option is much weaker than the rest. Obviously Horse combos with Imps, but it's still not amazing and I think you could get away with upping this to 2 Horses.
- on the downgrade option, I think it should say "up to $1 less". The funnest Analyst combo is Peddler, but you'd be pretty sad if there were no $7 costs in the game.
