I’m playing a lot of different stuff in Standard, but this might be the most interesting list. It’s a blue-white poison deck that kind of plays like a burn deck. I found it on magic.gg a couple of weeks ago and tweaked it.

Deck
5 [[Island]]
4 [[Plains]]
4 [[Adarkar Wastes]]
2 [[Seachrome Coast]]
3 [[Mirrex]]
4 [[Arcane Proxy]]
4 [[Fateful Absence]]
4 [[Bring the Ending]]
4 [[Prologue to Phyresis]]
4 [[Distorted Curiosity]]
4 [[Skrelv, Defector Mite]]
4 [[Crawling Chorus]]
4 [[Serum Snare]]
4 [[Experimental Augury]]
2 [[Deserted Beach]]
1 [[Eiganjo, Seat of the Empire]]
1 [[Otawara, Soaring City]]
2 [[Reject Imperfection]]

Sideboard
4 [[Knockout Blow]]
3 [[Elspeth’s Smite]]
2 [[The Wandering Emperor]]
2 [[Destroy Evil]]
2 [[Temporary Lockdown]]
2 [[Skrelv’s Hive]]

Advice for playing it:

Your opening hand has to be able to cast a Skrelv, Chorus, or Prologue, because those are the only ways to assign the first poison counter.

Serum Snare is one of the best cards in the deck. Bouncing a three-drop can buy you a lot of tempo. Also, in the late game, Arcane Proxy to flash back Serum Snare targeting the Proxy itself is a pretty good play.

The sideboard mostly seems intent on beating mono-red, and I sympathize with that goal so I didn’t change it much. I did once get to discard an Obstinate Baloth to Liliana, which was pretty fun, but I ended up taking out the Baloths for a couple of Skrelv’s Hives, which I’m hoping will provide a little more late-game viability against control decks. Might find room for a third copy.

I will say that this probably doesn’t beat the blue-black proliferate deck, because they’re trying to do the same thing you are but they have real permanents. I faced it once and it wasn’t a close game.

I haven’t been playing too much Standard, but I have my pet Golgari Titania Meld deck, and I have a so-so Mono-G list and a Gruul modified list.

That does look like a fun twist on the Rakdos that we’ve all been subject to for the last few months!

I haven’t been playing much standard over the last few months, mostly because of how incredibly stale the meta has gotten. This looks like it’s pretty fun though so I might give it a shot.
