Hey glad to see another Sliver deck. As it’s quite late I will keep this short, but I will try to give more suggestions at a later time.

For starters I would add Ancient Ziggurat in here, and also swap Mana Leak for another counterspell such as Disallow. I think that you may have just a few too many instants but I will give this a better look when I can.

But this definitely looks like a good start.

Hello Delta-117, just ordered Ancient Ziggurat.

For the counterspells I've been thinking about those that don't use double mana of the same source. I might even change Counterspell since it could cause mana issue.

I own Trickbind and Flusterstorm. Those could be usefull, I'll think about it.

I can't wait to talk about slivers with you guys. There's so much flavour to that tribal.

OP_Sigma I love the list. Great manabase, I have hardly any criticisms there. I do have one question though: why the inclusion of Urborg, Tomb of Yawgmoth? It's not like you're hurting for . I'd probably sub in something that produces , as you're going more control you'll want more access to that mana. Compared to my list you also chose to go a little lean on Slivers, removing Essence Sliver, Dormant Sliver, Homing Sliver and Basal Sliver. From these omissions it looks like you're going for a more aggressive strategy - potentially playing your commander a little sooner to get in that damage. I always think that Dormant Sliver is a great inclusion, but maybe Synapse Sliver would be more your speed?

This is an excellent build. I look forward to seeing what additional tweaks and adjustments you'll make going forward. +1 from me! I can honestly say that The Queen approves

Thanks for your input LVL_666

It's a great pleasure to have you comment here since you were such a big inspiration for my own deck.

You're right about Urborg, Tomb of Yawgmoth, I just bought Ancient Ziggurat and Cavern of Souls today, I'll make some space for them. Not sure if I'll keep Ancient Ziggurat though since it can only be used for creatures.

Draw might me an issue with my build, I'll consider adding something.

Since Dormant Sliver give my army defender and Synapse Sliver has a heavy CMC. Maybe I could add something in between.

I think Vanquisher's Banner could be good a good choice.

No defender effect on my army, I draw as I cast, my slivers get +1/+1 and I can use any color to cast it. The CMC is still high to my taste. What is your opinion about it? One major drawback is that I cannot cast it in instant speed with Quick Sliver.

I'll have to test it!

Honestly, I think you should keep Urborg, Tomb of Yawgmoth in, just because you have Sedge Sliver in the deck.

Hi Infral, I might switch it for Crypt Sliver.

Still have to test it a couple of time.
