Those Caryatids need to be replace with Striking Sliver . Caryatids can't attack, they aren't buffed by your other slivers, and just aren't for aggro. When necessary, Strikings can be mana dorks as well.

Yes i know Caryatids are dead weight in this deck by themselves. But how do I overcome the 5 color problem without mana creatures? Thanks.

The 5 color problem is solved by playing lands of every color. 4 Overgrown Tomb , 4 Stomping Ground , 4 Breeding Pool , 4 Temple Garden , and 1 of each non-forest basic land. the scry lands will slow you down too much. I would replace a garruk and a megantic with 2 more syphon slivers to balance the life loss

nevermind no basics, forgot about the mutavaults

I see what your saying. I would ask how the deck could afford to lose karyatid if the focus is shifted off green. I agree siphon is a lifeline when using the shocklands. Perhaps the planeswalkers could be rethought but after several dozen playtests karyatid seems essential. There just is not a high enough probability of drawing manaweft with 2 lands. Some shocklands are no longer standard. Thanks for taking a look

All shocklands are standard my friend.

Does born of the gods not cycle out return to ravinica? thanks

I think RTR cycles out in september or october.

-1 Syphon Sliver , -1 Megantic Sliver , +2 Sentinel Sliver .

I have found that vigilance is one of the most important parts of a sliver deck.

Thanks that is a good point. Dont have too much experience using it versus many opponents yet. I would also like to know what peoples opinion on galerider is. Thanks

Does anyone think there might be too much mana in this deck

Too much mana? No. I would say that being multicolor, there wouldn't be enough without your Manawaft Slivers. Should be okay...but lots of playtesting can answer that question for you. I would say that manafixing is rather easy in this format, so I wouldn't sweat that if you encounter issues. But on paper, looks good.

Galerider is super awesome. But consider what you may be missing if you drop the blue. If you find it easy to get it when you want, and don't have a problem drawing up the blue mana when you need it, then definitely keep running it. But it will be frustrating if you can't get it out.

Are there any spells at all that you're considering besides creatures? Draw, protection, tutor, etc?

I have been playing with some buddies running a mono black infect and a control token deck. My deck wins often vs the control due to just powering through and out-damaging the opponents. Infect mechanic is weird with this deck since lack of flying dense usually means i lose the damage race.

Mana is great if I get weft out with a couple dorks/tokens. Playtesting reveals by turn 5 or 6 im in a great place unless i get stuck on mana colors. I had 3x galerider in there before but it was too difficult to find that blue mana early, and my thought on flying were thorncaster could deal with bothersome flyers. Domri is fantastic in this deck. Xenagos was an experiement I havent been able to test yet.

With so many shocklands syphon became a lifeline but running 4 was too much for what mana base I have.

As far as other spells, yeah, they would be great but with domri in there it would diminish his effectiveness. If he ultimates its gg 9/10 times. I considered a garruk but without a solid ramp mystic+caryatid, nykthos hes too slow...

What i really need is a sideboard. Perhaps 1-2 copies of nyleas bow?Thanks for the input.

Need some pro comments!!!!

Put less slivers and drop red slivers. You need to protect your slivers. The more powerfoul slivers are green and white. And Galerider Sliver is our star.

Take a look on my sliver deck Born of Slivers

I win the Game Day on my store with my slivers deck.

You need some suport to slivers like Prophet of Kruphix so stronk.
