[Oops! all spells] Looking for suggestions/thoughts

I play mostly grindy decks (Nic fit, aggro loam) and have gotten pretty well known for it at my LGS, I was looking to throw together Oops! because it's cheaper, I have a fair bit of the cards (only big ones I need are 3 Mox, 4 summoner's pact) and would throw people for a loop if I played it every once in a while.

here is the list I've tentatively decided on. Goldfishing it, I like it. It has a pretty high "going off" chance, is a blast, and I like chancellor for that bit of "lolno" she provides. That said, a couple things of numbers seem to vary between some of the decks and I'm curious what other people think.

Namely:

Cabal therapies, seems to be 2-3

Narco, 3/4. I'm trying four now in case I draw one, or want another cabal sac before reanimating, which seems to be working okay

wild cantor/tinder wall: tinder walls are mostly for a bit of ramp, and for getting that mana for warrens in the SB, cantor lets me filter into black to I can ritual etc.

Summoner's pact: I've seen this number be 3-4

Street wraith: more filter, not sure I want it with chancellor

bridge from below: 2 seems cute to make sure I have enough to dread return, but I think it seems a bit much.

Thoughts? Advice?
