Just noticed, y u no 7 fetches? Also, both Reclamation Sage and Caustic Caterpillar are better than Harmonic Sliver.

Brood Sliver can get ridiculous with Synapse Sliver and some form of evasion

Harmonic Sliver to eliminate those pesky pillow forts and mana rocks

Fury Sliver to pound their faces into oblivion and double any triggers that you have upon damage

Toxin Sliver to discourage blockers

There's a lot of options in a sliver deck, good luck :)

For your sideboard, Necrotic Sliver and Harmonic Sliver are good options, as you are currently extremely vulnerable to prison decks.

Crystalline Sliver is vastly superior to Diffusion Sliver--well worth the substitution.

Ghostflame Sliver is pretty useless, unless Ugin, the Spirit Dragon or All Is Dust are common cards in your meta.

Aprikosen on Sliver - For the Swarm

mortalrage Thank you and i do understand your confusion and alsow yes i do open myself upp. Enchanted Evening is there because i have Harmonic Sliver in, that lets me destroy an artifact or enchantment when it and other slivers comes in to play. With Sliver Queen+Basal Sliver+Training Grounds or Sliver Queen+Basal Sliver+any mana making sliver combo i can make alot(inf) of sliver tokens and with that destroy my opponents land for example. If i don't want enchanted evening on my board anymore i can just dertroy it by playing a sliver as long as harmonic sliver is in play. Ramp is always nice but sence i have the two slivers that make so that other slivers tap for mana too i've never really needed any other ramp in the deck. Have been planing on upgrading the deck though, so who knows enchanted evening might get replaced.

@nitebane21 - Smelt might be a decent solution, though Harmonic Sliver sliver seems to solve both of those issues. They'd have to Chalice for 3 to stop it, which won't happen til late game. Explosives would just it if they went for 3, making it inefficient. Playing around those spells is pretty necessary as well, with Vial and holding back creatures to recover from a wipe. If they're running Chalice of the Void and Engineered Explosives because they're playing Stax or something similar, Swan Song helps to slow down the other parts of their deck significantly as well. If you're seeing those every game, it might be worth subbing in a few Smelt for Swan Song from the side board and going 4x on Harmonic Sliver. But only if you're seeing them all the time.

Hey, good job in the Commander league.

45x lands, this is too much land. 38x total lands is fine, consider cutting some lands? In there place include some land ramp that can also fix mana colors: Farseek, Cultivate, Kodama's Reach.

Haste is an ability you really want with Silvers, you already have Heart Sliver which is good, but I suggest also adding Blur Sliver and Firewake Sliver. Crystalline Sliver has already been suggested, but I'm going to suggest it again since it can be a game winning two drop Sliver. You already have Winged Sliver, but I suggest also adding Galerider Sliver more flying evasion and it's a one drop Sliver.

Harmonic Sliver can be devastating to your opponents. This Sliver is so good that some nonSliver decks play it because it gives you value when it ETB. The ability it gives Silvers when they ETB is not a may ability if your opponents don't control any artifacts or enchantments and you do then you must destroy one of your own. To prevent this play Darksteel Ingot. It's a three drop Rainbow mana rock with indestructible, it can't be destroyed. Target it with Slivers who ETB to prevent having to destroy your own.

A couple of underrated Slivers who can draw a lot of cards to consider adding: Synapse Sliver and Dormant Sliver. Hibernation Sliver is also underrated as it can save any Sliver from removal, board wipes, exile, etc. It's ability has no mana cost and doesn't target, it can be used with any Sliver who has shroud, you can save Crystalline for the cost of 2 life.

Sliver Queen has already been suggested and if you want to win with an infinite combo with Slivers then it's the best Sliver to include. Horned Sliver has also been mentioned, it's great with Sliver Hivelord giving it trample.

Amoeboid Changeling and Unnatural Selection can make any creature an opponent controls into a Sliver letting Overlord permanently gain control of that creature adding it to your Sliver army. Mirror Entity can be a Sliver, it's a Changeling and it can pump an entire army of Slivers. All Slivers get this power and toughness boost while keeping all their abilities.


Good luck with your deck.

Hey, good job defeating your son's Slivers, but holy high avg. CMC!

I recommend more lower mana cost defense to consistently shut down Sliver armies from attacking. Are you not playing the enchantments that prevent a lot of Slivers from attacking because of Harmonic Sliver?

Here's some suggestions:

Prison, Ganda and Crawl shuts down a lot of Sliver attackers. Consuls and Obedience shuts down haste. Thalia shuts down haste and also is huge disruption for a five color Sliver manabase. These cards are meant to slow down your opponent before you can wrath or get a finisher into play.

Other suggestions:

Sunmare is an indestructible Horse army in a can with Oloro. Elesh Norn is a great finisher and pairs exceptionally well with Godhead of Awe. Wipe the board of all your opponents' creatures even if they have indestructible and shroud.

Speaking from the position of this being my main deck I play I would like to make a few suggestions.

That's just what I'd suggest. You're call if you want to go that direction or not. The deck when built and piloted well is extremely powerful and sits at a tier 1.5 status.
