After a couple of goldfishes you're likely going to need more cards that grant hexproof. Legolas's Quick Reflexes is the best creature protection in green it's pretty pricey. Blossoming Defense & Royal Treatment are more accessible. Either could replace Overprotect.

Again this is pricey, but you have quite a bit of non-basic land search Cavern of Souls would be helpful to play Tifa Lockhart.

Might cut Cavern of Souls and Claws of Gix

Might add Springheart Nantuko and Lightning Greaves

PolyTheCakeEater: i've been playing slivers since before MH1. there's only space for 1 rainbow land, because rainbow lands don't provide the colors i need for the non-sliver spells, and don't count as a swamp for Sedge Sliver. sliver hive will be replaced by Cavern of Souls when i can afford them. other than that i rarely have problems getting the colors i need. 24 lands is what i need for Collected Company. i've tested the deck with 20 and 22 lands, and it wasn't enough. manaweft allows for early coco's, and i do have a haste enabler. dregscape and leeching would make the deck slower since i'd have to take out lords to make room. i used to use diffusion, but it got replaced by lavabelly.

Nice deck! I have some suggestions as I have played slivers for a while in modern. Land base probably will need some work. Use cards like Secluded Courtyard and Cavern of Souls as they let you use any colour. Additionally, 24 land seems like a lot especially with low CMC creatures, I run 20 land in mine. Manaweft is ok but can be unreliable without haste, but that is just my opinion. Dregscape Sliver and Leeching Sliver are solid options. Especially Leeching as it adds up really quick and has won me many games. Diffusion Sliver and Unsettled Mariner are also great at protecting your guys if the game goes longer. Feel free to check out my list on my profile. It's similar to yours. Great deck and keep at it bro!

This is precisely why Blasphemous Act goes in all of my red decks :) Seems super strong for the budget. Of course humans really wants Cavern of Souls, but beyond that I don't think an optimized deck will perform too differently from this one. Adeline, Resplendent Cathar is awesome for humans, and she's not TOO much around $5 I think. I'd also rec Dewdrop Cure (or Sevinne's Reclamation) maybe to replace your immortal servitude, I think these are both a tad more efficient and flexible. Nice budget list!

Going through the official WotC ban list and a couple of other sources, Cavern of Souls should be completely Pioneer-legal.

Ah, many thanks BioProfDude, I’ll take all the help I can get.

I’m glad you suggested Cavern of Souls—I originally intended to include it, but (long story short) when I added it to the deck it got flagged as illegal so I took it out. Idk the cardpool yet and I was reading mixed things, but it’s good to have confirmation.

Thanks for the sideboard suggestions too—I’ll roll with them until I get a feel for what I’m up against, and what works/doesn’t.

I will say Curious Obsession has been holding up well. I was running out of steam too soon and a set of those more or less put an end to that problem. I feel like I want to continue running them until something better comes along.

Get Lost and Sheltered by Ghosts are both new to me; I can see value in both, but between all the countermagic and faux removal (Skyclave Apparition etc) do you think they’re still necessary?

Well, I agree that additional dual lands are good, but Port Town is one of the worst. I'd suggest maybe 2x Cavern of Souls as you are heavy on spirits, and replace Port Town with 4x Seachrome Coast, and add 4x Adarkar Wastes. Probably 2x to 4x Hengegate Pathway  ^Flip would also be useful. I'd also add 2x Eiganjo, Seat of the Empire, 1x Otawara, Soaring City, and 2x Mutavault as your Supreme Phantom anthem will apply to an activated Mutavault because it is "all creature types."

I don't see any removal and that's needed in Pioneer. Probably 3x or 4x Get Lost would help. Probably 2x Sheltered by Ghosts would also be useful and would be great protection for your Spell Queller.

Honestly, I'd lose the 3x Lunarch Veteran  ^Flip, max out on Spell Queller and add 2x Mockingbird.

Just some thoughts-- hope this helps! +1 from me!

I would add that Curious Obsession is a good card, but I don't know that it is great in this deck. Try it out, but I could see cutting it to make room for the removal.
