Underground Sea is not modern legal, congrats on getting 4 of them though, maybe switch with the corresponding fetch? also... Jace, the Mind Sculptor

So.... if you take out all those lands like Scrubland and Bayou and whatnot, this deck is less than $200. If you want this deck, but at a lower power level and MUCH lower cost, cut these:
Plateau
Taiga
Savannah
Scrubland
Badlands
Bayou
Tundra
Volcanic Island
Underground Sea

This is both trash and illegal, (Sol Ring is banned) Counterspell is better than Cancel, and the deck doesn't use cards that are clearly much better, land base alone should use 4 Polluted Delta and Underground Sea, etc.

AlwaysSleepy for my deck there are a few things I have questions about.

For right now Candelabra of Tawnos, Timetwister, Underground Sea, Imperial Seal, Grim Tutor, Lion's Eye Diamond, and Transmute Artifact are out of my budget. (I am currently unemployed but will make the changes to the deck as I can).

I am currently using a few cards as pseudo tutors such as Muddle the Mixture, Shred Memory, Fabricate, Whir of Invention, and Tezzeret the Seeker .

I do think the lower cmc, storming route is faster and more consistent than what I am currently playing. Cuts that I think are quite obvious are Dig Through Time, Kozilek, Butcher of Truth, Pili-Pala, Grand Architect, and probably Tezzeret, Agent of Bolas, Gilded Drake, Clever Impersonator, Spellskite, Damnation, and Trophy Mage if I cut the Basalt Monolith + Rings of Brighthearth combo as well.

I have read your opinion on the combo as you think it is not necessary and I'm finding with 5 possible methods for infinite the deck is kind of cluttered.

I have been trying to make changes and will be putting Dark Ritual, Cabal Ritual, and Lotus Petal back in, I also really like how you have Dark Petition and I think I will definitely be adding it to my list since I don't have the other tutors. How do you also feel about Diabolic Tutor in my list since I have budget restraints?

Lands

I think I am going to cut Temple of Deceit, Fetid Pools, maybe Drowned Catacomb and 2 Swamps. I will add more islands for High Tide (or maybe not?).

I currently have a few cards coming in the mail that might help with the deck, those being Vesuva, Boseiju, Who Shelters All, and Sunken Ruins (as sunken is pretty self explanatory).

Also , I am curious what is your opinion on Mishra's Bauble? Do you think it would find a place in our decks? Or is it a bad cEDH card for deck thinning and cantrip draw?

I would absolutely love to have a chat with you on discord or some type of voice communication to talk about your deck and the playstyle too since quite honestly I was trying to avoid storm at the beginning of my career as I thought it was too intense and that I would not understand it.

Have you considered putting in the entire cycle of Polluted Delta style fetch lands? They don't have to get basic lands so you can get the Underground Sea style dual-lands or basics and thin your deck out. Plus they don't come into play tapped nor does the land they fetch.

Removed a lot of cards with a casting cost of more than 1 colored mana. It was often too difficult to play spells.

By using the original double lands it'd be possible to change some basic lands for these: Badlands, Evolving Wilds, Myriad Landscape, Terramorphic Expanse, Underground Sea, Volcanic Island

TheHelvault on Would crystal vein be a ...

For your level of competitiveness, I'd say Crystal Vein is very acceptable. Turn 1: Island, Turn 2: Crystal Vein, Show and Tell, Emrakul, the Aeons Torn, etc. Seems good for kitchen table legacy to me haha.

I ran Tin-Fins for a kind of competicasual thing my playgroup had going, and it worked fine with some Gemstone Mine's instead of Underground Sea. I wouldn't worry too much about using Crystal Vein.

xyr0s on Competitive Zombie deck ?

2 months ago

I don't know how to put this politely, but... erhm... what do you know of legacy, pretzels? I'll admit that I'm no afficionado of legacy, but this does not look like a competitive legacy deck. Your clock is too low to just race your way to a win (can that actually be done in legacy?), you have no protection against combos that put a hasted Griselbrand into play turn 2, and so on. While getting to play Carrion Feeder is an upgrade over a modern zombie deck, the decks you want to compete against get so much more than a few +1/+1 counters on turns where they have mana to spend.

It's probably a smarter move to start looking for a replacement for Carrion Feeder, and stay in modern. Or invest in some Underground Sea and Polluted Deltas... and some Wastelands... and a set of Thoughtseize
