Underground Sea Discussion

sylvannos on Need opinions on a casual ...

Yeah "budget" and "Legacy Esper deck" don't really go together. Unless, of course, "budget" means "under $4,000." Underground Sea and Tundra are going to cost a bunch, even if you only play 2~3 of each. I'd avoid blue altogether if you're trying to play Legacy on a budget.

That being said, there's also much easier ways to kill creatures repeatedly in Legacy or more efficiently. You're actually not as concerned about more than a few creatures per game against most Legacy decks.

I'd recommend looking into Deadguy and Pikula decks. There's budget versions of those decks out there and they can easily be upgraded once you have either a better budget or win prizes at local tournaments.

Spirits on Kess, Dissident Mage

3 weeks ago

Cards that I don't like:

Darkwater Catacombs | In a turn 4/5 build, it's too slow. Basically useless in some situations and opposite of mana fixing

Fetid Pools | Enters tapped needs strong abilities, maybe turn 8 cycling would be good, but in a Turn 4/5 build, it's not a turn 1 through 4 land so shouldn't be in there

Great Furnace | I think you can fetch , a single on Turn 1 though 4 is terrible

Tolaria West | Great land, but what does it tutor for you that's a combo card, Mana Crypt is ok, but none of your combos are land based, I wouldn't run this. If you needed to fetch a specific land for a combo would be ok.

Big Cash $$$ Money Land Upgrades (Have fun with these): Underground Sea, Volcanic Island, Wooded Foothills (cheap!), Arid Mesa, Misty Rainforest, Verdant Catacombs, Marsh Flats

I would go down 1 net land to 36 as well.

Cut list:

Devastation Tide | Miracle is too random, want to control your spells not have them control you. And it's a sorcery, as an instant it would be ok.

Cryptic Command has a pretty High CMC with , it's instant so it's better than some of the other sorcery/creatures, but could be a problem. It's VERY good card though, I would keep it worth the hard casting cost.

Scroll Rack mana sponges, it's too random, and too slow for turn 4/5 deck

Tolaria West go down a land!

Tutor Plans?:

Beseech the Queen >> Necropotence or Show and Tell or Laboratory Maniac

Demonic Tutor >> Necropotence or Omniscience or Enter the Infinite

Fabricate >> Sensei's Divining Top or Seat of the Synod or Mana Crypt (Add) (Not really that utility, doesn't pull any combo pieces, could be a cut list, I would probably cut this card)

Gamble >> Necropotence (High Risk, High Reward) or Show and Tell or Demonic Tutor

Imperial Seal >> Necropotence or Omniscience or Enter the Infinite

Merchant Scroll >> Lim-Dul's Vault or Intuition (Add it) or Mystical Tutor

Personal Tutor >> Enter the Infinite or Show and Tell

Tunnel Vision (when used to tutor) >> Mizzix's Mastery! (Downside is it misses Omniscience so need something it can hit to put a card from graveyard into hand, best would be a card like that with flashback) OR Tunnel Vision >> Yawgmoth's Will. If it discards a Past in Flames get a couple shots. I think Kess, Dissident Mage can cast the Overload cost from the graveyard for Mizzix's Mastery too if you do get it looking for the Yawgmoth's Will which then cast the Yawgmoth's Will.

Throw an Imperial Recruiter in there as well to Tutor a Laboratory Maniac heh

Trinket Mage >> Sensei's Divining Top or Mana Crypt (Add). He doesn't pull combo pieces so he can be cut. Once you have Mana Crypt he only cost you , without it, he's not awesome.

Lim-Dul's Vault >> Any Tutor cluster or Any two combo cards, hard to plan this one because it relies on random cluster, or a Necropotence

Long-Term Plans >> Necropotence or Omniscience or Enter the Infinite

Mystical Tutor >> Show and Tell or Enter the Infinite

Tainted Pact >> Entire Library with Laboratory Maniac, or a specific solution, or to find a final combo piece

Vampiric Tutor >> Necropotence or Omniscience or Enter the Infinite

Summary: Harder to tutor items (Enchantment) should be priorities, Necropotence or Omniscience. Kess, Dissident Mage let's you recast and pull another item in most cases to finish the combo Omniscience + Enter the Infinite, lots of tutors pull Show and Tell for you.

Street Wraith, Doomsday (Don't need Lion's Eye Diamond you have other ways to win with it) honorable mention for adds.

Intuition, Mana Drain, Force of Will, Grim Tutor, Mana Crypt are all-stars.

Capture of Jingzhou and Temporal Manipulation are good too, but not necessary, you're really just trying to combo win with Show and Tell + Omniscience + Enter the Infinite would focus on getting there.

Don't need Thought Scour, it builds the graveyard for Kess, Dissident Mage but it's too dangerous if it pushes a Omniscience or Necropotence

Frantic Search is better if you have a way to recur-it, like a Nivix Guildmage, but it does give you more control on the discard. The problem arises when you only have 1 card in hand, becomes the same issue I'm sure you experience with the Scroll Rack.

Leyline of Anticipation can be cut, but I like it. Helps with protecting the top-decking tutors. Actually works against Kess, Dissident Mage though if you delay cast, in some random cases.

Dreadbore could just be another tutor that pulls Hero's Downfall they do the same thing anyway (or a Yawgmoth's Will if you need to recast Hero's Downfall and have used Kess, Dissident Mage. And it's a sorcery (YUCK)

You need the Lightning Greaves and Swiftfoot Boots for Phage the Untouchable and Laboratory Maniac. You could lose the Swiftfoot Boots since you do have Artifact tutors, but I bet they are pulling mana sources not boots.

Phyrexian Metamorph could go too if needed. 9 Artifacts, and 7 creatures, BUT, I would keep it to copy a Vendilion Clique or Snapcaster Mage or Laboratory Maniac to win.

Temporal Extortion could be wasted spell, since i doubt your doing the extra damage, but in multi-player perhaps it may resolve due to politics.

Time Warp could come out too if needed, high CMC extra turns. Useful for mid-range play though.

Need to research a way to bring a card from graveyard to hand, if it has flashback, that would be AMAZING!

Sgtpopnfreash on Kess Final Storm

I think Im jealous of your Imperial Seal and Grim Monolith!! Nice score. From there I think an Underground Sea might be in your future. Anyway, correct me if Im wrong but this is primarily a Doomsday deck with Aetherflux Reservoir as a backup. Doomsday is awesome because it takes 1 blue mana to win if you have the right cards in your deck and 4 islands. You should try to build your deck twords that goal. Islands should make up about 85% of your land base not because of High Tide but because of Gush\Doomsday piles. From there High Tide gets stronger and your deck will have a win by turn 4 or 5 with protection 70% of the time.

Kjartan on UW Control - Legacy

If you're going to run off color lands to support Engineered Explosives, why not run two different instead of two identical. Swap a Volcanic for an Underground Sea perhaps.

Also, you could make that 2nd Scalding Tarn a Polluted Delta just on case an opponent names it with a Pithing Needle or something alike.

AkromaPhage6 on Tell me about legacy

Legacy is an amazing format, and by far my favorite. The back and forth interaction can be even better than modern (imo). Yes, there are games that there is no interaction at all, but for every one of those games there is one where you and your opponent are basically playing chess in your heads.
The format can be difficult, and you may look back on a game and go how did I lose this match? And the answer can sometimes be that I fetched the wrong land on turn 1. The rules depth and interactions will teach you an immense amount about mtg though. I've grown by leaps and bounds in my gameplay just by playing this format every week (luckily, my lgs has a weekly event). A huge portion of becoming good at this format is knowledge. Knowing your deck intimately is a default. You'll also benefit when you can identify your opponents deck quickly. With the opponents first play (even if it's just a fetchland), I'm narrowing down the possibilities. By their 2nd play I've probably narrowed them down to usually 1-3 decks. Reanimator is a great first choice (although Underground Seas are pretty expensive).

Howdy! I have a NM Scrubland from Unlimited and am looking for a LP Underground Sea from Revised. I can make up any value with other RL pieces and we can trade pics via text or email. Let me know, thanks!

rockleemyhero on LF: underground sea, volcanic island

1 month ago

Looking to trade for a PL/HP/MP conditioned revised Underground Sea or Volcanic Island .

I have specific, unlisted value cards outside of my binder specifically for ABUR duals:

Force of Will

Grim Monolith

Wheel of Fortune

Snapcaster Mage

Crucible of Worlds

Aluren

Captain Sisay

Sylvan Tutor

Cabal Coffers

Mystic Gate

Dark Depths

and several shocks and fetches. Of course anything in here as well. All of the $50+ cards and fetches are specifically reserved for these duals so please don't offer me other cards for them (unless it's a Timetwister or something...)

Sgtpopnfreash on Fast Combo Breya

1 month ago

So I have tried your build and it combo's off faster that is its strength. It also has less shitty mana rocks however it requires a "better/more expensive mana base.I only have Scrubland, Volcanic Island and Underground Sea. I moved to playing this combo because my playgroup is all Chain of Vapor, Pongify, Swords to Plowshares. I got really tired of having worldgorger get ruined.
As for Necropotence. Its not in there because if your going to tutor for a draw spell its Ad Nauseam every time. It probably does work in this build but its kinda inconsistent in my mind when you are mainly trying to Ad Nauseam and the triple black can make it difficult to cast when it does show up.
