Here's the results of a Playtest I just did.

High Tide, Sphere of the Suns, Ponder, 2 Frantic Search, 2 Island

Took the play

Turn 1: Island, Cast Ponder into Frantic Search, High Tide, and Lonely Sandbar. Draw the Frantic Search, topdeck High Tide, pass

Turn 2: Draw High Tide, play Island, cast Sphere of the Suns, pass

Turn 3: Play Lonely Sandbar, enters tapped. Tap Sphere to cast High Tide. Tap an Island leaving U floating to cast the other High Tide. Tap Island and leave U floating to cast Frantic Search into 2 Breakthroughs, discard a Frantic Search and a Breakthrough. Untap 2 Islands and Lonely Sandbar.

Tap Island and Lonely Sandbar for UUUU, cast Breakthrough with X of 4. Draw Fraying Sanity, Island, Anticipate, and Ponder, discard Island. Tap Island for UUU and cast Frantic Search into Anticipate and Opt, Discard Opt and an Anticipate. Untap 2 Islands and Lonely Sandbar.

Tap Island for UUU and cast Ponder, seeing Frantic Search, Island and Island. Draw the Frantic Search. Tap Lonely Sandbar and Island for UUUU, leaving UUUU floating and casting Frantic Search into 2 Islands, discard the Islands, untap 2 Islands and Lonely Sandbar.

Spend UU on Anticipate into Island, Island, and High Tide. Put High Tide in my Hand, bottomdeck the Islands. Spend U on High Tide. Spend U on Opt into an Island, bottomdeck it and draw an Island...

Tap Island for UUUU and leave UU floating to cast Anticipate into Island, Island, and Breakthrough, put Breakthrough in hand and bottomdeck the Islands. Tap Island for UUUU and cast Breakthrough with X of 4, draw High Tide, Cloud of Faeries, Fraying Sanity, and Careful Study, discard Fraying Sanity and Careful Study.

Tap Lonely Sandbar for U and cast High Tide. Cast Cloud of Faeries for UU, untap both Islands. Tap Island for UUUUU and cast Anticipate into Sphere of the Suns, Sol Ring, and Opt. Take Opt, bottomdeck the other two. Cast Opt, bottomdecking an Island and drawing Traumatize!!!

I am one mana short of being able to cast them both... And they are the only cards in my hand. Big sad. I will have to play Fraying Sanity on them for now, and then hit them with Traumatize next turn, praying draw mana and they don't have counterspells?

Turn 4: Draw Sol Ring. Theoretically cast it and then Traumatize my opponent and win the game once the Fraying Sanity trigger resolves.

Overall thoughts: If I had an Island instead of a Lonely Sandbar as my 3rd land for turn, I would have had the mana to finish the game up on Turn 3.

This kind of makes me think about an alternate, Surveil version of the deck, with the same High Tide engine, but more Surveil cards that thin your deck of unnecessary cards in case you shuffle with a Ponder later. I'd maybe swap the Opts, Anticipates, Breakthroughs, and for some combination of Consider, Curate, Mission Briefing, and Enhanced Surveillance. Mission Briefing is really powerful because it lets you recast your Frantic Searches. I'd also swap the Sandbars and a couple mana rocks for Islands.

Additionally, if we're thinking Surveil, and we want to bounce our Cloud of Faeries, how about Unauthorized Exit and Unexplained Disappearance?

Thanks for the comment and reading the description bjgivesbj! Yeah, Forced Fruition is great at flooding people with options while simultaneously functioning as a one-sided doomsday device.

I have considered Mind's Dilation and Well of Ideas before, but I haven't included them for the same reason I haven't included Eye of the Storm, they're just a little high on the CMC. I might consider putting Mind's Dilation in, but the other two are too high cost to be that symmetrical.

I have considered Grip of Chaos, but it introduces just a tiny bit too much chaos for this deck. This deck functions best when its Disruption is reliable, and Grip of Chaos just messes with our plan too much.

Cultural Exchange might work, since often this deck doesn't care about who controls the creature (like Ian), just that they are on the battlefield. But I don't know, it might be too situational to be good. (I do use this card in my Xyris deck, great in that.)

Storm Cauldron is interesting - it means if people take lands out of a Share the Spoils or Thieves' Auction pile, that those lands would end up going back to their owner. Possibly... But this might attract too much aggro our way, without us being able to actually shut down reliable play.

Shared Fate is interesting at first, but that would just turn into everyone putting the gun to my head and exiling my library when I force them to draw a bunch (like with Forced Fruition. They cast two spells and exile fourteen cards from my library? And then cast Pongify from those cards to get seven more? HA!). It has WAY too much potential to backfire once people realize what they can do. Nope.

How about Give / Take?

How about Genesis Wave instead of Rishkar's Expertise? The Wave is more beneficial in decks with a lot of permanents like yours, and will trigger a lot of Landfalls.

How about Realms Uncharted? Maybe in place of Sylvan Scrying?

Hey, another recommendation I just realized as I was reading the card: Sylvan Library. The effect is worded, "choose two cards in your hand drawn this turn." That means effects that draw you extra cards on draw step, like from Kami of the Crescent Moon, would feed into that pool, effectively expanding your selection of cards to put back on your topdeck. In the Kami example, instead of putting 2 of 3 cards on your topdeck, you're choosing 2 of 4. It's an interesting synergy that adds more asymmetry to the Group Hug effects, besides Sylvan Library being a fantastic way to generate card advantage.

From the Gatherer Rulings:

12/8/2022	If you control other triggered abilities that allow you to draw cards during your draw step, you can choose to order Sylvan Library's ability before or after those abilities. Triggered abilities controlled by other players will resolve before triggered abilities you control.

Oh! And one last stealing and blinking forbidden lore card is Nephalia Smuggler. Note that its effect returns the card to your control, not its owner's!!! So you can bounce a creature that is stolen temporarily by an effect like Callous Oppressor, and then it comes back under your control for good...

Well, until you give it away of course.

Recommend cutting Inspiring Refrain for it.

Also, how about swapping the Conjurer's Closet for Thassa, Deep-Dwelling?

I know you are trying to cut cards, but I have to recommend Coveted Falcon, for the sheer power of how many permanents you can Give to the Poor at once, and the card replacement you get for them as well.

If I had to recommend a cut, I'd say Helm of Possession. The sacrifice cost is a bit steep.

How about Surgical Extraction or Extirpate? Same effect, one can be paid with life, the other has Split Second. A benefit of this effect is that if you choose a nonland card, you can potentially remove up to 3 land cards from its owner's deck deck, making your Mind Funeral effects even more potent. Your choice between these two would probably depend on the amount and types of interaction in your work pod.

Edit: Considering your manabase is mostly focused, Surgical Extraction might be the go-to.
