I would try Acidic Sliver .With Mana Echoes + Sliver Queen = infinite damage. I would get rid of sliver that share the same ability.Harmonic Sliver seems very useful.Homing Sliver can be useful if your general gets shuffle into library. Or costs too much to cast,etc.I would try to fit in Magma Sliver ,Sedge Sliver , Spectral Sliver ,Telekinetic Sliver ,Vampiric Sliver and Virulent Sliver .I don't think you need Amoeboid Changeling , Fury Sliver , Blur Sliver ,Plated Sliver , Synchronous Sliver ,Gemhide Sliver ,Sidewinder Sliver and Spined Sliver .They seem costly and you have one in there that do the same thing or seem underwhelming to me.

This deck sorely needs some card searching or tutoring effects. Diabolic Tutor is less than a dollar. If you want to pay though, Demonic Tutor is just astounding in it's power level. Tooth and Nail can create a very dominant board state if you play it right; (think Bonescythe Sliver and Megantic Sliver in the same turn, or literally anything that fits the situation. You could also use some draw power in here. Sign in Blood is a super cheap card. Phyrexian Arena is also amazing. That card is less than $10. there's also Increasing Ambition and Diabolic Revelation to consider. If you don't relying on black, I think you deck is slow enough to include Ring of Three Wishes . I'd also include Kodama's Reach and Explosive Vegetation .

Thanks for your suggests guys. I definitely tried to include many of your suggestions. Grimgrinner, if you had to pull two more cards for the Kodama's Reach and Explosive Vegetation what would you pull?

Awesome deck! Those are the best slivers out there and very appropriate enchantments and sorceries. It might not hurt to throw in Coalition Relic or Mana Reflection . And just for laughs, Door to Nothingness just because you can.

I need to make my Slivers look more like this.

There is a card i cant think of at the moment that mils yourself until you hit a named card, then you put the card in your hand. you can do that with patriarchs bidding to reanimate like half your slivers and be awesome

That definitely sounds good. If you think of the name let me know. I'm definitely interested in it. Ill see if I can find it.

try green suns zenith

Tunnel Vision ?

Genesis Wave

chameleon colossus is great cause all those buffs make it a big creature and with trample insane

just to see what inferiorchild was talking about, Chameleon Colossus . If you want to link cards, make sure to use the [ and ] twice.

Sweet. Thanks again everyone for the comments. Ill definitely be using Tunnel Vision and will try to find a spot for the Genesis Wave and Chameleon Colossus .

Five colors? Prismatic Omen .

Oh! And Virulent Sliver . Because 40 points of life or 21 Commander Damage are too high! Why not 10 poison? xD

Prismatic Omen . Yes. And I have thought about using Virulent Sliver a lot, but Im still not sure, I just don't know what I would cut for it. Ill look again though. Its definitely a good card.

I think you could take Crypt Sliver off... if your slivers already have shroud from Crystalline Sliver they can't be targeted to regenerate, so...

i think you should take out some basic land and throw in Reflecting Pool

and why is Tunnel Vision in there

Mirari's Wake

Tunnel Vision is there for milling myself into Patriarch's Bidding or Faith's Reward and then drop a ton of cards onto the field at one time.

Faith's Reward would not work in this situation as the creatures must go to the grave from the BATTLEFIELD, if you mill, they go for the grave from the LIBRARY

Sorry misread the card.

Crystal Quarry is good for playing your Sliver Overlord and Doubling Season is better than Aggravated Assault because Sliver Queen Manaweft Sliver and haste from a sliver unlimited mana

Plague Sliver :P
