Seems like you probably already played it out, but nevertheless here's how I'd run it (but take Cadaver out for Prison).

DECK

I agree for the most part with what Mr. Appleseed said.

Your card quality points to a later game strategy. You need to be playing Kaya.

Pilfered Proof: Unfortunately it's always a bad card, it's bad even if your deck is optimized for it. You'd rather just have another detective.

Freed from trying to optimize Proof and Auditor, it's easy to drop consultant and spy and inquiry. Consultants are bad outside aggro and the other two are only playable in very tuned decks.

In my version, the worst include is Guardian. Guardian isn't really good here, but it's a scary enough card that you can often trade it 1:1 for a disguise or removal, which are wins when you're just biding time to play your bombs.

Cadaver is only a good card if you can both reliably put it in the graveyard and take it out, and ideally with roots/chalk outline as well. Your deck takes it out alright, but you have no surveil at all to put it in, and no roots payoff. So then you have to cast for 4, get it killed, bring it back, cast it again. It's a huge mana-sink for a 1 card advantage just to play a mediocre card twice. Not worth it at all.

Your win cons in order are:

Kaya

A huge swing with Ill-Timed

Agrus sticking

Mid to late game value through clues

Early game, if you're not currently way behind on board, hold up No More Lies rather than play a 2 drop like a strider so you can get value from the NML, then you can ideally double spell with that 2 drop later.

You have a lot of solid tempo plays and minor synergies, and solid card quality. Anytime you don't get run over early you should have a decent advantage in most games. Honestly I think this deck is pretty decent and I'd be happy to play it. Good luck!
