Underground Sea

Land — Island Swamp

Welcome to the club, Danutercisd!

For being a first deck, I'm impressed to see the Mana Crypt, Cyclonic Rift, Fierce Guardianship, The Meathook Massacre, Underground Sea... I'm going to guess that budget isn't a major constraint here.

One of my pet cards for this sort of thing is Geth, Lord of the Vault. It offers milling, reanimation theft for creatures and artifacts, and a pretty big evasive body.

If you like instant-win combos, both Bloodchief Ascension and Duskmantle Guildmage set up full-deck milling and lots of damage with the Mindcrank in the deck.

Another suggestion is to diversify your copy/theft effects. There's a lot of ways to copy opponents' creatures, but you can take them directly with Control Magic, Beguiler of Wills, and similar effects, steal and copy spells with Talent of the Telepath or Twincast, or yank something from their deck with Praetor's Grasp. You opponents are probably going to be doing things beside throwing creatures around, and being able to react to different threats and take advantage of different opportunities is always good.

Very solid for a first attempt at deckbuilding. You have a clear grasp of what you’d like the deck to do, and a capable strategy to get there (which is arguably the most important part of deckbuilding).

That said, Legacy is a fast and brutal format, so depending on the specific context of where you’d play this, results may vary. For example, dual lands costing thousands of dollars are typical in sanctioned play, and provide an overwhelming advantage versus any other type of land. It’s a case of, ’If you have them, you need to run them’.

Sideboards are also tuned to a higher-than-usual degree of efficacy, with specific answers for specific problems.

If this is for friendly matches only, then most of the above can be disregarded, although maybe consider looking into some countermagic since you’re in blue.

Used to think proxies were a form of cheating, and swore not to play with anybody who proxied. I first warmed up to them when a friend ran some for cards he owned, just, didn't want to bother re-sleeving every single game. Made sense.

I changed my tune overnight after playing someone whose turn1 was something like Underground Sea, Mana Crypt, Grim Monolith in a "casual game with jank". Bullshit. I realized then and there that it was about money. I had considered proxies cheating because it invalidated the money I had invested into cardboard. But I was never going to own a Mana Crypt, or anything over fifteen bucks for that matter. Limiting the cards I allowed myself to run, in a meta where someone could drop $1000 on turn 1...that's just pay to win. That's not the kind of Magic I want to play.

Printed off several pages of cards that same night.

As Gidgetimer suddenly looks emaciated & bug-eyed, he/she sneaks out that OG Underground Sea, strokes it, & calls it "my precious"... :) -- in order to show us a complete 180 degrees from that awesome comment :)

Honestly though, I think stock concern stuff is mostly just corporate/investor swordplay going on. Even if Hasbro miraculously tanked, or shut down the MtG cash cow, then in the age of recycled ideas & reboots there would be another company popping up with the MtG property in short order to turn record profits after the game was "gone" - It would be one "last" reunion tour type of thing. How often do you hear that now? :)

I have a Legacy Mono- Burn deck that doesn't use any Fetch-lands. Because of which, despite being completely foiled-out, all 75 cards cost less than a single copy of Underground Sea..

I call that "budget"..

Ardees on Gates? Nine Fingers Keene Competitive

1 year ago

If you are aiming at 'competitive' in the technical sense of the term (as in 'cEDH' or 'competitive EDH'), like the title seems to suggest, I see many staples missing that unfortunately make the deck quite far from being competitive.

Artifacts: you should be running at least Mox Diamond, Chrome Mox, Mana Crypt, Sol Ring, Arcane Signet, Mana Vault, Jeweled Lotus, maybe even Grim Monolith and Lion's Eye Diamond.,

Tutors: you are missing Vampiric Tutor, Imperial Seal, and Worldly Tutor and Green Sun's Zenith if you run any combo, win, or strategy whatsoever based on creatures. You could also add Wishclaw Talisman and Solve the Equation, and, although not a tutor, Peer into the Abyss, which works quite nicely with Thought Vessel.

Lands: any competitive deck plays true duals, namely Underground Sea, Bayou, and Tropical Island. Same for shocklands and at least 6-7 fetchlands in a 3-color deck like this one. You could also consider lower the number of lands, depending on whether or not you want to keep the Gate strategy

Protection: any competitive deck that plays blue automatically plays top-end counterspells, namely Swan Song, Arcane Denial, Force of Will, Force of Negation, Pact of Negation, Fierce Guardianship, Mental Misstep, An Offer You Can't Refuse, and Flusterstorm. You are also missing key cards like Cyclonic Rift or Chain of Vapor. Needless to say, ideally a competitive deck playing blue also plays Timetwister: not a counterspell but a must card (yeah, the price is another topic of conversation).

Creatures: I understand the Gate theme but you are missing some high-value creature cards in here, most notably Dauthi Voidwalker, Malevolent Hermit  Flip, Lotus Cobra, Azusa, Lost but Seeking, Tatyova, Benthic Druid, Ramunap Excavator, Dryad of the Ilysian Grove, Oracle of Mul Daya, Elvish Reclaimer - to name a few. Much depends on the strategy of your deck, although don't let keywords aligned with your strategy (e.g. 'Gate') fool you into thinking some cards are good for that.

Enchantments: a few staples in the current competitive meta: Rhystic Study, Mystic Remora, Sylvan Library, Burgeoning, Exploration, maybe Abundance and Necropotence

Removals: you could most definitely swap some of your removals for something better and more competitive, such as Force of Vigor, Nature's Claim, Abrupt Decay, Assassin's Trophy, and more.

Now, I totally understand there is a budget situation going on with upgrading to competitive MtG (spoiler alert: MtG is a pay-to-win type of game, research confirms), but generally the term 'competitive' sticks to decks that, to the very least, include most if not all cards mentioned above - without mentioning the fact that any competitive deck needs running at least one winning combo. At this stage, your level is more looking towards casual. This isn't to criticize you or anything of course, pretty interesting build, just not really a competitive deck in its strict sense.

If you want to try the competitive experience, my suggestion is to proxy cards by printing them online - this should cost around 10 bucks on colored and good quality paper, and effectively save you more than 7k worth of cards.

Ardees on Ramses, First of the al-Ḥaššāšīn

1 year ago

andycampbellgg Thanks! This is the best way I could envision a Ramses deck being anywhere near highly optimized / competitive. Assassins tribal is just not powerful enough; most assassins are really not worth it. To fully upgrade this deck you'll still require Underground Sea and Timetwister, which you would swap for an Island and for Windfall. I'm running neither here as this is a deck a own in real life.
