Sliver Overloard is a better commander cause he can "tutor" for the queen/legion Heartstone /Training Grounds makes queen/overlord ability cost only 1 or 2 instead of 2 and 3 to activate giving you a infinite mana combo with the queen and Basal Sliver also giving you infinite sliver tokens really, Wild Pair is great in this deck cause with no pumps out a Muscle Sliver gets out a Might Sliver ( but your not running him so any p/t 2 sliver) and then your Megantic Sliver will come out as a 7/7 getting your queen or legion, or with no pumps out you can use your overlord to get the queen and when you play her out she will get the legion for FREE!! Just a few things to think about

That definitely stands, but on the turn queen comes in, you can tap your slivers with [card:manaweft sliver] or [card:gemhide sliver] and populate your field for a 5-turn win.

The reason i chose [card:sliver queen] over [card:sliver overlord] is simply the art :)

nothing else :D

The other suggestions are awesome, and i will look into them! Thanks!

Wild Pair works amazing! Can't believe i overlooked it.

I also pick Training Grounds Because Enchantments tend to be trickier to get rid of :P

You suggestions are much appreciated! Thanks

Sliver Overlord isn't always a better commander than Sliver Queen , they both have their place in the game. Sliver Overlord is great if you want to consistently hit the same creature combos every time you play, Sliver Queen is great if you want to roll the metaphorical dice and see what abilities you can get out and then just populate the hell out of the field.

I would suggest looking into Eldrazi Monument , since you can put out cheap creatures fairly consistently late game it wouldn't be a bad idea and it would save you from board wipes, even your own.

Also, I would suggest Coat of Arms over Door of Destinies , it works instantly, rather than having to wait for you to cast spells.

In terms of planeswalkers, check out Garruk, Caller of Beasts . If you can ultimate hit with a deck like this, you pretty much win.

Finally, Dementia Sliver is really not that good, especially in a singleton format. Swap it out for something to either boost your guys like Might Sliver or one of the trample slivers (which I think you should have anyways) Horned Sliver /Groundshaker Sliver

PS. Invest in a better mana base. It's too small to start with, and you're missing some things that are pretty important. Cavern of Souls should be an auto include, along with things like Crystal Quarry , Reflecting Pool , the shock lands, fetches and ABUR duals if you can afford them, and once you have your colours more readily available you can throw in some more utility lands. Things like Haunted Fengraf , Maze of Ith , and Reliquary Tower .

Your suggestions are much appreciated!

I have revamped the deck now, including the cards i do not actually own - for tappedout.

The previous problems were simply owning the cards and or budget :)

With Eldrazi Monument i could even put in a few more mass removals for the sake of a few less-useful slivers, or artifacts

whats up with no more than 1 of each card?

@kadonian thats the rules for EDH/Commander only 1 of any card other than "basic" lands

Oh i didn't know that LOL.

Thinking about replacing Wild Pair with either Parallel Lives or Doubling Season since they have more synergy with Her Highness

Hell no, Wild Pair stays.

Personally I can't STAND Crystalline Sliver as it ruins several epic combo's like Fungus Sliver + Thorncaster Sliver for pump and of course Amoeboid Changeling + Sliver Overlord combo won't work with Shroud... Keep in mind you only have 2 or 3 sac outlets to remove Crystalline from play and if I'm against this deck, I will let it live as to keep you from sliver thief. Shadow Sliver is another one that I disagree with unless you KNOW you can win that turn and lets face it... you never know that for a certain. One Fog can ruin that.

On another note I see you skipped over a few fantastic slivers and I don't know why... Necrotic Sliver is PERFECT removal especially if you have queen as the commander since you can token poop. Pulmonic Sliver is the best sliver to keep what you want after board wipe effects, which happen often against us Horde lovers, and Frenetic Sliver is missing. Again, PERFECT for boardwipes and removal. Or even just blocking before it dies...

Heartstone is missing too. We all know the infinite sliver combo that requires either the Stone or Training grounds (with a mana sliver, haste sliver, and sliver queen). If you put in one more of the ability then you will be more likely to hit it when you need it. Speaking of infinite slivers Screeching Sliver is missing which can mill every opponent you have. With Intruder Alarm That can be all in the same turn you produce infinite tokens.

The deck has been updated in the meantime, really the only thing that hits it is mass removal.

Crystalline Sliver - good point there, haven't run much of the interaction combos, and rarely get spot removal from my enemies, but i notice the Thorncaster Sliver +Fungus Sliver now, good call

Shadow Sliver already removed

Necrotic Sliver acquiring thisPulmonic Sliver also

Screeching Sliver - already in the new version of the deckFrenetic Sliver - already in the new version of the deckHeartstone - already in the new version of the deck

and regarding Intruder Alarm - i fucking love this card, thank you for the excellent spot!

Armed and Dangerous ?

I'm sorry but i really don't see Armed / Dangerous doing a huge impact =\

Call to the Kindred?

Anything that puts some of them on the bottom of your library and filters slivers on top could quite possibly remove those few non-sliver cards that you really need and put them on bottom, and that hurts

Screeching Sliver+Basal Sliver+Sliver Queen+Fires of Yavimaya= Infinite mill

lazarusdraigon thanks for reminding me to put that in keycombos
