Ok I've made some changes to the deck.

I removed:2x Mnemonic Sliver 1x Talon Sliver 1x Victual Sliver

I then added 4 Dormant Sliver

I playested with a friend but it seems that 4 of them are too much. I've removed 2 keeping the other 2.

Now I have 2 empty slots any sugestions?

Thanks

+1 from me.

I like Shifting Sliver in my deck.

I considered that one as well. But he is a bit expensive mana wise. That's why I didn't use him.

Thanks for your reply :)

I've removed 2x Dormant Sliver and added 1x Winged Sliver and 1x Harmonic Sliver .

At this time I'm considering the possibility of removing the other 2x Dormant Sliver and added 2 more Mana Echoes but I'm still unsure about that.

What do you guys think?

Thanks in advance

This deck is a fun concept and I LOVE slivers but you have few kinda fatal flaws in this deck.

Run Manaweft Sliver over Gemhide Sliver in the event of a mirror match

Run Galerider Sliver over Winged Sliver it's cheaper for the same card

Run Syphon Sliver over Essence Sliver it's cheaper and a little weaker but definitly a faster play and more efficient

You don't need 20 lands but that does not matter as much

Don't run basic lands try to only run cards that enter untapped and give all colors if you can Sliver Hive is one of the best examples of this

If you have time though come few mine and leave your own comment and I could always use an upvote :D Sliver Rush

You may actually also want to include some colorless slivers to take advantage of echoes better you could search with Sliver Overlord, mana with Mana Echoes, then play in an infinite combo plus Dormant Sliver for draw if you have it.
