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

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.

Returning to MTG I would like to play Grand Prix and different types of regional tournaments to eventually play in Pro Tour someday. Is there any restriction for certain type of cards that can be used? For instance, I have Underground Sea along with other lands that I used since the mid 90's but on Card Kingdom they write sometimes that a card is not tournament legal. Does anyone know how this is handled and is there eventually a resource on the internet to double check it before making an investment in specific cards?

Went up against what I assume was a Time Vault / Manifold Key combo. I can’t recall my opening hand perfectly but my opponent lead with Underground Sea and Mox Jet into Ponder and Imperial Seal . I could have countered something but my general rule of thumb is to counter what is tutored rather than the tutor. Land, go. They mana rock into Timetwister which I assume is what they tutored as it would shuffle away anything else. I hit that with a Force of Negation and took the turn. Land, go. From there it was much slower. I got out Teferi, Time Raveler on turn 3 and Dovin, Hand of Control the following turn. Countered a Demonic Tutor and responded with Dack Fayden . Dack pulled us into a follow up Jace, the Mind Sculptor . At that point, they were low enough that we could ride Jace’s to deck management, maintaining our counters until Narset, Parter of Veils and Kasmina, Enigma Sage . We continued to keep our opponents top deck and our own managed, eventually completing the crew with Oko, Thief of Crowns coming down for an additional Fractal. Our opponent managed to pull a Tinker while we took the turn off but we had plenty of counters ready at that point and was able to stave off and go in the lethal offensive.

It was only one game but I would definitely have brought in Ashiok, Dream Render having seen Imperial Seal , Demonic Tutor , Tinker , and Tezzeret the Seeker .

Any reason not to play Underground Sea?

Also, Merfolk Secretkeeper seems better than Wall of Lost Thoughts to me if you aren't running many/any swamps. Also worth considering Gemstone Mine. Not a huge fan of Darkwater Catacombs instead of just like a fetch land, but I might be wrong.

St0rmeZ - You can shave off about $2500 just by cutting the 5 big reserve list cards ( Volcanic Island , Tropical Island , Underground Sea , Warrior's Oath , Wheel of Fortune ). The deck would still be expensive, but it would be more in line with your average commander deck.

Regardless, this deck seems (and performed) awesome. I would love to see Mirror March in here for the memes and occasional explosive plays.
