TypicalTimmy on Well of Eternal Knowledge

3 months ago

Of course, the owner of Well of Eternal Knowledge is at a huge, massive, unparalleled advantage being in WUBRG because they have access to all colors and thus all spells available to them. Meanwhile, someone in Dimir or Naya or mono-white are at a serious disadvantage because they can not as easily cast spells other players have. However, with enough clever planning, you can cast another player's artifact that may open up colors for you, or play their lands which offer more mana options.

It would be significantly slower for players who use lesser amounts of colors, but it is doable. And the balance aspect comes from the other three players will likely team up Archenemy style against the owner / controller of Well of Eternal Knowledge for this very reason. And if a single card forces a 4-player deathmatch into a 3v1 war for survival, then I think the card can get away with such power.

For example, if a player draws their card for turn and thus must reveal the top card of their library, and it is an Indatha Triome, the next player could immediately play it, assuming the player who owns the Triome has already played their land(s) per turn. If in rotation the next player is Dimir and could really use access to the and the Triome offers, it's theirs for the taking. But perhaps that Dimir player actually wants to crack their Drowned Catacomb to search for an Underground Sea. They pass on the Indatha Triome. Then the next player can try their hand at it. If the next player needs it, they can have it.

Maybe one player has in their hand a Fellwar Stone. Perfect! This will open up all colors, basically.

Maybe someone reveals a Beast Within from their hand and another player decides OH HELL NO and immediately casts that targeting Well of Eternal Knowledge.

So the balance is there - you merely need to be clever about it.

macdeath on Vintage PO

-1 Underground Sea is asking for trouble to cast the key black cards. This type of deck can struggle against Wasteland + Null Rod decks, relying on Mox Opal and 1 Underground Sea is not where you want to be.

-Thassa's Oracle does not belong in the deck whatsoever and neither does Noxious Revival. You are already packing Tendrils of Agony and Time Vault which are much more suited to the deck. Noxious Revival is just worse than Snapcaster Mage especially in a deck with Paradoxical Outcome

-Seat of the Synod is usually only played to make Thoughtcast / Thought Monitor viable. It makes the deck super soft to Null Rod effects.

-Urza, Lord High Artificier is okayish but worse than Monastery Mentor or Tinker>Sphinx of the Steel Wind. Also, Urza's Bauble is pretty bad in Vintage.

rshistorysmuf on Proxies, yay or nay?

As someone has previously mentioned. Unless I can trade up, and up, and up, I would like to have a Mishra's Workshop around 2K but there are reprints in Vintage Masters and Master edition IV (haven't seen them), Candelabra of Tawnos - 900 reprinted Vintage masters (have not seen it), Underground Sea 400 reprint, Volcanic Island 400, Plateau 150, Gaea's Cradle around 500.

It's a shame but when you see IHYD playing such uber stuff, you wish why can't I play these in commander. Do we go and buy knock off versions?

plakjekaas on Proxies, yay or nay?

I really don't like playing proxies myself. I really want to own the cards I play, by personal preference. I picked up my Gaea's Cradle for €375, because I really hated looking at the basic Forest that I scribbled "Gaea's Cradle" on with a sharpie.

But I do realize how lucky I am with plenty disposable income to spend on this game, and I would never scold or exclude anyone who doesn't choose to spend their money this way. I do have decks that can hold themselves at a competitive table though, so if you're not restricted by budget by playing proxies, I would like to know before playing, so that I can adjust my expectation of how powerful that will make your deck.

Proxies are fine if you explain why you're running them in the rule 0 conversation, it's not fine to hide them and pubstomp everyone with cards that were presumed too powerful for the table. If I did run proxies, I'd at least bring one deck with me that didn't have them, just to accommodate for when my opponents don't like the use of them. Some people still consider them a touchy subject after all.

Only use proxies if they enhance your gameplay experience. Using proxies is a slippery slope into using the most powerful cards because there's no treshold to not run them anymore. The resulting imbalance in power level may ruin gameplay at your playgroup. There's a difference between proxying a single Doubling Season because that's a pretty expensive card that's vital to certain strategies, and opening with a proxy Underground Sea into a proxy Mana Crypt into proxy Intuition, just because you can. As long as you're aware of and able to communicate how you feel about that difference, there's no reason I can't have fun playing with you.

ninja8244 on Thrasta's Storm Primer

Hi Profet93 great questions! Let's break it down.

  1. Recycle is used for card draw once you have the Food Chain + Thrasta, Tempest's Roar combo going. It allows you to go through your deck really fast. It 100% should not be played before then or else you are going to fall behind fast.

  2. I Gemstone Caverns for the same reason somebody might put Chrome Mox in their deck, free mana. the reason I chose Gemstone Caverns over Chrome Mox is because of artifact hate.

  3. Elvish Spirit Guide has been super useful a couple of times. The one green mana can make all the difference depending on the scenario.

  4. So, in CEDH 90% of the decks I go against have blue and black in them. Blue is super good against this deck because counterspells can totally ruin our combos. Choke is primarily good because most of the decks that run blue run it via dual lands or shock lands, because of this for example they may be also cut off of black if all they have are Underground Sea s and cards of the sort.

Suggestion: Replace Dimir Guildgate with Underground Sea

I will not take no for an answer

Polaris on Tournament Legality

It all depends on what format you're playing. The common tournament formats are Standard, Pioneer, Modern, Legacy, and Vintage.

  • Standard is a rotating format where only cards printed in the last two years of expansion sets are legal (in this case, Eldraine, Theros Beyond Death, Ikoria, M21, Zendikar Rising, Kaldheim, and soon Strixhaven).
  • Pioneer is a nonrotating format that includes all sets from Return to Ravnica and newer (so starting around fall 2012).
  • Modern includes cards printed since original Mirrodin.
  • Legacy and Vintage include the whole of Magic's history; the difference is that cards are not banned in Vintage but instead they can be restricted (only 1 copy in your deck).

To be legal in a format, a card needs to have been printed in an expansion set since the beginning of that format (collectors editions, From the Vault, Commander releases, Masters sets, etc do not count except for Legacy and Vintage). Underground Sea had its last expansion printing in Masters Edition IV, so it's only legal in Legacy and Vintage.

If a card has been reprinted in a newer expansion, it becomes legal in the formats that expansion is legal in, and you can use any copy of it in that format. For example, Serra Angel is a card from Alpha, but it has been reprinted many times, most recently Dominaria. This makes it legal in Pioneer and Modern, and you can use any copy, even Alpha versions, in those formats.

To check legality (and for card searching in general) I highly suggest the website Scryfall. When you look at a card on Scryfall, it shows whether or not the card is legal in the most common formats. You can also see the current market price of different printings, and you can use the advanced search to look for cards matching certain criteria (including limiting your search to cards legal in a specific format).

Major tournament formats are:

Standard - cards from the last two years (roughly)

Pioneer - cards since Return to Ravnica

Modern - cards since 8th edition

Legacy - cards since Alpha, some cards banned on power level

Vintage - cards since Alpha, no cards banned on power level

EDH - cards since Alpha, no more than 1 of each card in a 100 card deck

So your Underground Sea would be legal in the last three formats.
