Underground Sea Discussion

Boza on Does WotC Have a Responsibility ...

And one more thing:

  • Underground Sea is not the card you want to "flip for profit" as a speculator. What you want to target is cards with extremely low supply where one person or group can scoop up the whole supply at once - like Moat for example.

Literally no-one plays moat. It is a 1-of in some sideboards at best and a decent commander card. But it jumped 500% in a week due to a buyout. However, Moat is not worth 1000$ - nobody is buying at that price (people are barely buying it at the 800 it is currently) - it is simply due to supply shortage and speclative offerings that it costs as much.

This is entirely different from Underground Sea - people play the dual lands. The price for them is a combo of short supply and extremely high demand. Not due to speculation.

I don't care how inexpensive cards are, so long as it means more people playing the game. This notion of putting the game behind a paywall is nonsense.

The entire purpose of separating MtG into Type 1 and Type 2 is because Black Lotus hit $100 on the secondary market. While it's more profitable for WotC to make chase cards to sell booster boxes, it's harmful to FNM and other event attendance. I'm worried most about prices for Standard, Legacy, and Vintage.

For Standard, new players can't play the format meant for new players when it costs $400+ for most competitive decks. The two cheapest decks in the format are RDW and White Weenie, which are roughly $150 to $200, depending on the build. Even that is a steep price for people who just want to try the game out.

For Legacy and Vintage, the Reserved List is going to kill those formats. Obviously, the people who play those formats aren't concerned about prices. What they are affected by is the fact speculators and investors are buying up RL cards so they can hold them while their prices increase. Every time someone buys an Underground Sea to speculate on its price to try and flip it for profit, that's another Underground Sea that will never be played. This puts a hard cap on the number of Legacy and Vintage players.

So long as there aren't any viable decks that can be built for cheap using cards not on the RL, Legacy and Vintage will continue to shrink as players can't find cards because buying those cards up and sitting on them is more cost effective than using those cards to play in events.

Fatal Push, Underground River, and Mental Misstep are under $5 dollars, so I'm not going to give replacements on those, but for Ancient Tomb , City of Traitors , Glimmervoid , Inkmoth Nexus , Mox Opal , and Mox Diamond , I'd replace those with 3 Islands and a Swamp and add a River of Tears and Spire of Industry .

BTW, did you mean Underground Sea when you typed Underground River ? In which case I'd add Underground River over Underground Sea anyway.

For Force of Will , I'd use Steel Sabotage , it acts as an occasional counter and protection for your artifacts if you bounce them in response to removal, or to reuse them in case of Renaming a new card with Revoker or getting another cast trigger on Sai, etc.

Spellskite is harder, for this Lightning Greaves would be my pick, but Swiftfoot Boots additionally works for budgetary reasons.

Arcbound Ravager is the hardest. Any other artifact based finisher you'd like can work, but Mirrodin Besieged is my favorite.

Hey gvazdaus,

How has The First Sliver performed? My concern is that it would cascade into something I'd rather not cast at the moment.

Good question. So, there have been a few moments where I cast First and end up with a counterspell or Toxic Deluge . Fortunately there is a "may" clause where I can simply not cast it:

When you cast a spell with Cascade, exile cards from the top of your library until you exile a nonland card whose converted mana cost is less than the spell's converted mana cost. You may cast that card without paying its mana cost. Then put all cards exiled this way that weren't cast on the bottom of your library in a random order. - source

Before First was even printed, my deck was pretty much designed to incorporate it. Top deck manipulation is an important theme in this deck, and therefore I can set up multiple castings during my upkeep or at a moments notice depending on what I have on board. Ad Nauseam effects wouldn't hurt to include, but I think there are better options. Worldly Tutor and Enlightened Tutor are must haves if you are running First , in my opinion. Scroll Rack can set you up for some really great plays if you have in hand what you want to Cascade onto the field - like a Mana Echoes for example.

Durdle Time - yeah...I too am concerned about that. What I try to do is consolidate library shufflings and searching into just one instance. For example: Turn 1, I play a Polluted Delta . I tell my playgroup that I am going to crack it for an Underground Sea and play Vampiric Tutor . I put the tutor into my graveyard, while making the motion on the board that I have tapped the Sea . Once I do that, I pass turn get my cards, shuffle my library and double check to make sure my boardstate is legal. My playgroups appreciate this, and when someone stops to scrutinize or ask questions I welcome it - because I could have easily made a mistake. So yeah, try and consolidate shuffling/interactions with your library into one event - but always check with your playgroup first if that is okay.

I love your deck, and I'm currently trying to build it, however, some of the cards are a little out of my price range. Force of Will , Badlands , Scalding Tarn , Underground Sea , Volcanic Island , Grim Monolith , Mana Crypt , Mox Diamond , Mox Opal , Imperial Seal , Time Spiral and Wheel of Fortune .

I would appreciate it very much if you could provide any suggestions or themes I should look for in replacements.
