Amulet of Vigor would help with any cards that come in tapped like the gates.

Shard Convergence Could help too

As long as you're including the gates and Maze's End I'd suggest throwing in a Scapeshift . Ghostflame Sliver can also be useful if something has protection from a color that's shutting down your Sliver Overlord . Unnatural Selection is also a useful card for Sliver Overlord .

Thanks for the suggestions. I like the Unnatural Selection combo. Scapeshift is interesting. Ill definitely think about using it,

Training Grounds and/or Heartstone can cut down your Slivers' activated abilities. Primal Surge would probably be really effective since you only have 2 non-permanents.

Training Grounds is a must. Thanks for that. And how could I forget Primal Surge . Even though its CMC is kinda high, if I play it....

What would you pull for Primal Surge ?

Probably Savage Lands . 38 lands should be enough to easily run this, even with 5 colors. Besides, with Gemhide Sliver , Manaweft Sliver , Chromatic Lantern , and the things you can use to drop Slivers from your hand, you should be fine.

Casting Primal Surge shouldn't be too difficult, especially in a Sliver Commander deck with both Gemhide and Manaweft Sliver.

No love for Megantic Sliver ?

I used to play an EDH Slivers, I've played slivers a lot, they are my favorite tribe.

Is only one card you are underestimating here and is Basal Sliver

Think about this:

Sliver Queen + Training Grounds + Basal Sliver

Then you can bring in every card in your deck, and you can, win with your Necrotic Sliver

That is a sick infinite combo there. Ill definitely make room for the Basal Sliver . As for Megantic Sliver , I just forgot about him. He is going in. Thanks all.

If you had to pull 2 slivers which ones would you pull for the Basal Sliver and the Megantic Sliver

Darkheart Sliver and Victual Sliver do pretty much the same, I would take away one of them, Victual Sliver in my oppinion, because of his activation cost consuming Mana and Slivers.

Battering Sliver and Horned Sliver do the same, so I'd change Battering Sliver for Megantic Sliver .

Also you may want Blur Sliver and possibly Mutavault

Mutavault for sure. I just need to spend 15 bucks on a land. lol. Definitely going in though.

ever thought of using Lim-Dul's Vault ?

Its interesting, I dont think it fits though. Cool card though.

if you think about adding planeswalker there is two suggestions for you. Sorin Markov (which will make you lose friends really fast) and Garruk Wildspeaker (extra mana is always nice and his ulti makes your slivers deadlier if it is possible) on another note think these three will be really killer on your deck World at War Relentless Assault and Waves of Aggression or any spell that gives you extra turn

I have a Sorin Markov so i might find some space for him, and World at War is amazing. Ill definitely try to make space for that. Any suggestions on what to pull?

Mana base needs some work. If you run 5 colors there is no shame in CIPT lands or pain lands like City of Brass or miscellaneous lands like Exotic Orchard .

I don't really see the point in AEther Vial or Belbe's Portal or Sol Ring . Darksteel Ingot is a possible replacement. Although, I'd rather just run Cultivate or Kodama's Reach or something.

Lastly, your deck doesn't really look like it can win in multiplayer. You appear to just vomit out slivers and then wait for somebody Wrath of God you so can look around with minimal draw functions and one recursion spell. Alternatively, you get behind and have no real removal of your own and thus you stay behind. In my opinion you need to re-examine your creature base and cut at least 10 slivers. My advice is cut the ones with negligible effects such as life gain or mill, win more effects that add counters or create more tokens.

IDK, Zur the Enchanter into Engineered Plague into Copy Enchantment .

Galerider Sliver instead of Winged Sliver

And Blur Sliver instead of Reflex Sliver

Mana Echoes + Sliver Queen = infinite slivers

please add door to nothingness i would cry if you won like that

I ABSOLUTLY love this deck. I am making this as soon as i can afford it. My brother is secretly making an EDH deck behind my back so this will show him not to mess with me

Thanks man. I really appreciate the comment. But this deck would not have been possible with out all the suggestions and feedback you guys give me, so thanks to all of you. Good luck against your brother man, Im sure he will hate playing against this, which is just the way we want it. lol
