Neotrup on Basic swamps and swamps

3 weeks ago

A swamp card is any land card with the subtype swamp, such as Swamp, Overgrown Tomb, or Underground Sea. If you're instructed to search your library for a swamp, such as by Liliana of the Dark Realms' +1 ability, you may find any such card.

A swamp is any land with the subtype swamp, as the aforementioned lands typically are while they're on the battlefield, but that may be changed by other effects. If Blood Moon is on the battlefield, of those lands only Swamp will still be a swamp. If Blanket of Night is on the battlefield all lands will be swamps.

A basic swamp is a land with the supertype basic and the subtype swamp, such as Swamp and Snow-Covered Swamp, assuming nothing odd is going on. If Blanket of Night is on the battlefield other lands such as Island, Snow-Covered Mountain, and Wastes will also be basic swamps.

Glad to see your a fan of the wonderous hive also k_drake. I also happen to have a Sliver Overlord deck of my own, although mine is still a lot cheaper. Keep in mind however that LVL_666 has also chosen to bling out this deck nearly entirely, and thus the price you see on here is much more than what it would could actually be with a non-foil, non-masterpiece/expedition version of the decklist.

The first and most obvious things to avoid would be the original duals, (i.e Underground Sea, Volcanic Island, Tropical Island etc...), next you make do without Mana Crypt, Cavern of Souls, Wheel of Fortune, Yawgmoth's Will, and Mana Drain which should bring the deck down by a huge margin.

There's is such a vast amount of lands to choose from that could be suitable early on, including: the vivid cycle (Vivid Crag, Vivid Grove), the tri-lands (Seaside Citadel, Savage Lands, Jungle Shrine, and so on), then there's ones I use to use like Transguild Promenade, Exotic Orchard, Forbidden Orchard, Rupture Spire, Evolving Wilds / Terramorphic Expanse, Ash Barrens (highly recommend), and the panorama cycle (Bant Panorama, Jund Panorama, Esper Panorama, etc).

You can then make use out of the signets, Golgari Signet, Izzet Signet, etc) and perhaps use most of the combinations (prioritize the ones that have green). Anyways I know I have told you a Lot of information to read and consider, and so let me give you a good visual of what a starting point could look like:


A Study In Slivers: Toolkit Sliver Commander

Commander / EDH TolarianCommunityCollege

SCORE: 365 | 70 COMMENTS | 120873 VIEWS | IN 401 FOLDERS


This deck by the Professor I do recommend you consider as a base, and from there start as I have done, which was slowly acquire all the slivers (and imo minus the queen, and legion at least at first), I actually was quite fortunate to receive most of the slivers needed for my list from a friend who had their very own Sliver Overlord deck and he sold/traded me eventually most of it as he was getting out of commander. I picked up stuff like Gemhide Sliver, Manaweft Sliver, Necrotic Sliver, Harmonic Sliver, Heart Sliver, Galerider Sliver and Crystalline Sliver if I recall first by cash and standard trades.

Then I got a few things like a Chromatic Lantern, Merciless Eviction, Heartstone, and Training Grounds for more additions. Eventually I started with getting the shocks and fetches (the khans fetches are cheaper) again the cheaper ones like Windswept Heath, Wooded Foothills, Temple Garden, Overgrown Tomb, Hallowed Fountain, and worked my way up having more than half of them (I'm currently only missing 3 fetches and 3 shocklands).

I got my Sliver Queen and Sliver Legion from the same friend who took apart his sliver list (it's unfortunate he sold it's entire manabase and then just kept the slivers before I even met him at my lgs though), after I had all the rest of the creatures and up until that point I focused more on an aggro/voltron strategy. I bought him some very pricey modern staples (2x Chalice of the Void before there reprint and traded an Ulamog, the Ceaseless Hunger for these 2 slivers and to nearly finish a whole deck to play for modern :)

You can then later like i'm soon about to do myself soon I think, start to buy things like a Mana Crypt, Mana Drain, Demonic Tutor, Wheel of Fortune, etc to make the deck more competitive.To give you an idea where i'm at, here's my decklist (I'm missing 16 cards in all from it) also that's cheaper than what you see here:

I did not exactly plan on writing essentially a book on this for you lol, and so I apoligize. In summary start by acquiring if you don't already own any these above suggested lands, and start acquiring all the slivers you can, I recommend get ones like Sliver Hivelord, Diffusion Sliver and or Crystalline Sliver, Blur Sliver, Gemhide Sliver + Manaweft Sliver, Bonescythe Sliver, Syphon Sliver, Heart Sliver, Harmonic Sliver, Galerider Sliver + Winged Sliver, and others like Predatory Sliver, Sinew Sliver, Muscle Sliver all of which are pretty cheap. Then you will want Chromatic Lantern, plenty of signets, Darksteel Ingot, Commander's Sphere, Fellwar Stone, maybe the newly reprinted Coalition Relic which is a bit cheaper now. Then start upgrading the manabase(Mana Confluence, City of Brass, Unclaimed Territory, Sliver Hive, Ancient Ziggurat are all a good start. Then go with maybe getting the filterlands which thankfully have been reprinted and are now a lot cheaper,(Flooded Grove, Twilight Mire,...) and the shocks/fetches prioritizing the ones for green like Breeding Pool, Overgrown Tomb, Windswept Heath, Wooded Foothills because you will want green I would say more than any of your colours to cast stuff like Manaweft Sliver + Gemhide Sliver, Kodama's Reach/Rampant Growth/Cultivate etc. Once you have most if not all of the slivers and the mana base then you can go back to refining the deck with medium to high end upgrades like Mana Crypt, Volrath's Stronghold, Demonic Tutor, Vampiric Tutor, Pact of Negation, and such. Personally in my case i'm refraining from the original duels for budget reasons myself as I can't ever see myself getting enough use out of them to make them worth it fully. Anyways I hope this gives you lots to think about!

(Final note), consider Spirit of Resistance at least initially if you think you can either protect it with counterspells or in a meta where enchantment removal won't be an issue :)

Epochalyptik on Does Quicksilver Fountain effect Snow-Covered ...

An Island is any permanent with the basic land type "Island," including Island, Snow-Covered Island, Moonring Island, Underground Sea, etc.

An effect will specify if it cares about a card's name rather than its type.

Command Tower is pretty important in any five-colour EDH deck.

Couple suggestions to make:

  • You should post a link to this deck on the Challenges and Articles forum. The thread will stay on the homepage longer, and gather more attention than a decklist will.

  • You should probably set a budget for individual cards, lest you receive suggestions of Underground Sea.

Also, if you are interested, SirFowler's deck, The Budget EDH Name Game was built using similar methods. It's pretty amusing, and worth a look if you find community deckbuilding fun.

Ok, are you playing in MTGO or paper? Either way, here are the cards I might take out, either because they are too slow, or they are better in multiplayer (or they are just bad). Dark Salvation, Prized Amalgam, Noxious Ghoul, Liliana's Reaver, Army of the Damned, Crux of Fate, Vanquisher's Banner, Noosegraf Mob, Vindictive Lich, Dread Summons, Endless Ranks of Dead, Altar of Dementia, Sol Ring, Undead Alchemist, Kindred Dominance, Geralf's Messenger, Never / Return, Call to the Grave Grimgrin, Corpse-Born. You could definitely take out others as you play the deck.

Here are some good cards that would be good to have, but not all will make the cut. Rings of Brighthearth, Basalt Monolith, Talisman of Dominance, Arcane Denial, Counterspell, Lim-Dul's Vault, Swan Song, Pact of Negation, Snapcaster Mage, Jace, Vryn's Prodigy  Flip, Toxic Deluge, Damnation, Leyline of Anticipation, Vedalken Orrery, Teferi, Mage of Zhalfir, Thought Vessel, Glen Elendra Archmage, Commander's Sphere, Solemn Simulacrum, Gilded Lotus, Cyclonic Rift, Overwhelming Denial, Search for Azcanta  Flip, Forbid, Bloodchief Ascension, Urborg, Tomb of Yawgmoth, Underground Sea, Sunken Ruins, Cavern of Souls, Ancient Tomb.

I'm sure there are many other cards that would be great in the optimized version of this deck, but these are the ones I can think of right now. Also, I am not extremely familiar with the current meta of MTGO(?) 1v1 commander, so there may be cards that are good because of the meta. You will want to do some research and you will definitely make changes as you play. Have Fun!

Thanks for the quick response!

Can you tell me if there are any combos I am overlooking for Mimeo himself or if he is just there to represent Sultai colors? Any information about notable excludes would be great too. I picked up this deck with the exception of a few things like Bazaar of Baghdad, Underground Sea, and Tropical Island and I am just wondering if there are a few notable excludes that I could play over somethings outside of my price point. For example I own a copy of Diabolic Intent and I don't currently have a copy of Grim Tutor. One last thing I am curious about is how the FlashHulk string works without the inclusion of Phyrexian Delver.

Thank you for your time and the deck list!
