CleverRuse For the Harmonic Sliver problem just run some "Grounders" like Darksteel Ingot and Darksteel Axe, ones obliviously better than the other but if you want more chance's to that effect then sure run the axe. Also i forgot one more Phyrexian Altar I know its not Ashnod's Altar but its just another mana fixer that you might want.

I feel real dumb for forgetting about Training Grounds... Probably just going to replace Heartstone entirely. My problem with Harmonic Sliver is that it's effect is mandatory, and my deck relies on artifacts/enchantments too much. Having him in play makes going infinite with Queen & Mana Echoes effectively impossible. Crib Swap is nice removal early on, but once the slivers really get going the shapeshifter I give them will likely be a bigger threat than what I can remove.

A tutorable removal is real nice, though... Sideboard it is! Thanks for the input!

Love the deck got a couple of suggestions though Harmonic Sliver just a Aura Shards on a stick. Maybe Training Grounds if you want your abilities to be cheaper and second copy of Heartstone. A Paradox Engine for another copy of Intruder Alarm to help untap your slivers to tap em again to play another sliver when you have a Gemhide Sliver or a Manaweft Sliver on the battlefeild already. Also i know you wanna keep it permanents only but Crib Swap is to good when you have Sliver Overlord as your commander, since you can find it with its ablity to search for a sliver card. Once again awesome deck!

Thoughts on Aura Shards v Harmonic Sliver? It's protected less but won't fire-back on your own cards

Velly velly niiiiice! The mana curve is a thing of beauty. But how do you finish people off? Just grind them into the dirt with a neverending sequence of Zulaport Cutthroat triggers and Harmonic Slivers etc?

I also think you should take advantage of the white and stick in a Pull from Eternity in there. To lose Shirei, Shizo's Caretaker to a cheeky Crypt Incursion would be a crime!

One I think would be cool is one called Apex Sliver. It would include:


Legendary Creature - Sliver

Sliver creatures you control have hexproof.


If not that though some other ideas I had were either a sliver that grants undying, although I'm thinking this could be too good and i'm not sure what you would call it as Necrotic Sliver already exists which would have been a good name. Or a sliver that allows your slivers when they enter to fight target creature similar to how Harmonic Sliver works.

Other ideas include one possibly called Blooming Sliver.

Creature - Sliver


At the beginning of your upkeep, put a +1/+1 counter on sliver creatures you control.


Noxious Sliver

Creature - Sliver

Whenever a sliver creature you control dies, you may put a -1/-1 counter on target creature.

So I'm going to preface this: I played Sliver Overlord in Commander for probably 2-3 years, so I definitely enjoy using him as a Commander, and will try to impart the best card suggestions I can based off of my own experience:

1): You need to run Intruder Alarm. It is probably the best enchantment you could run in Sliver Overlord EDH, and I'll explain why in a spoiler, copied directly from my own deck's page:

What you need is 5 Slivers total, two of which should be Sliver Overlord and Manaweft Sliver or Gemhide Sliver. Pay 3 to tutor out a Sliver with haste (if you have an open mana from any non-Sliver source available after casting Intruder Alarm, you require only 4 Slivers), namely Heart Sliver, and cast it. Then, proceed to cast every single Sliver in the library from mana costs 1 and 2 up. At the end of this, they should be getting something in the range of +50/+50 with multiple forms of evasion, indestructible, vigilance, double strike, shroud, etc., so you could probably swing one or two at each opponent to end the game.

If you're afraid of Fog or something similar, once you've pulled every Sliver you want out of your library with Intruder Alarm, you should control a shrouded and indestructible Sliver Queen, Cautery Sliver, and Gemhide Sliver/Manaweft Sliver, among other little dudes (you can literally just go get these, though, if you want the win to be quick). You should have lots of extra mana from the Intruder Alarm loop mentioned above, so you can begin dumping tokens from Sliver Queen whenever you pull her out, which will untap all of your Slivers again- thus giving you the ability to make as many tokens as you want. So, with infinite tokens, you also have infinite mana, which means you also have access to infinite damage from Cautery Sliver. Keep Hibernation Sliver in mind because it can essentially prevent opponents from interacting with your creatures during this entire step. So long as you're careful, it pretty much takes a Krosan Grip on Intruder Alarm to stop this train from rolling, so the more leeway you give yourself in terms of mana, the better (anything without split second just allows you to activate Hibernation Sliver or cast another Sliver at instant speed (Quick Sliver) to continue this process until you're satisfied).

Okay, now with that out of the way, I also suggest Paradox Engine, and for the same reason as the above: Paradox Engine is basically Intruder Alarm Lite that only you get to use if you control Gemhide/Manaweft.

Other enchantments I would suggest would be Mana Echoes, which goes infinite with Sliver Queen and is just generally absurd with Overlord (put a Sliver into play to collect tons of mana to tutor up more Slivers? Yes please). Rhystic Study is a solid draw engine for EDH, and Cryptolith Rite is Gemhide/Manaweft number 3.

Sliver suggestions:

Hibernation Sliver. Because exile is a thing, and it can protect your creatures with a measly 2 life. Also, it works extremely well with Intruder Alarm/Paradox Engine. A Merciless Eviction would completely ruin your day, while Hibernation Sliver and a sac outlet can help reduce the impact significantly.

Basal Sliver. Infinites with Sliver Queen.

Firewake Sliver. Basically better Blur Sliver as it can function as a sacrifice outlet against mass-exile.

Horned Sliver. Gives trample- basically a cheaper version of Battering Sliver.

Harmonic Sliver. All-important enchantment and artifact hate, don't run without it.

What I suggest removing to fit these in:

Battering Sliver. Horned Sliver is significantly better as it costs half as much for the same effect.

Megantic Sliver. While it's a nice Sliver and the buff is good, Sliver Legion costs less, does more, and I can see no reason as to why you'd ever be happier to see Megantic vs Sliver Legion as even by itself, Legion is larger (a 6/6 vs 7/7. With 2 Slivers, you'd have an 8/8 and at minimum a 2/2, vs Megantic with a 6/6 and a 3/3- Legion always gives the larger buff at a cheaper mana cost). For this reason, I see little purpose in keeping Megantic when, if you're going to tutor out a Sliver, it's going to be Legion.

Quilled Sliver. It's just not that great. Hibernation Sliver will surely do more for your deck as it is a much better defensive tool

Spined Sliver. You can do better than this card; Horned, Harmonic, etc., do a lot more.

Vampiric Sliver. While not awful, it still has an ability less useful than most others, and less useful than Intruder Alarm or Paradox Engine.

Toxin Sliver. I removed this one from my own list recently; I found it was, generally, just an overcost and worse Venom Sliver. This could easily become Intruder Alarm's slot, for example.

Anyway, hope this helps. There are a few more suggestions I have (like Seedborn Muse because she's insane with Sliver Overlord and Quick Sliver), but these are all for right now since I've already typed a bunch. Have fun, and if you want to look at a list for inspiration, here's my Sliver Overlord list here: Za Warudo! (Sliver Overlord Aggro).
