Thinking, well Sliver Hivelord give you indestructibility, and that's something good always, except for Path to exile and similars. Once I could win against a Wurmcoil Engine thanks to it. So I think this will remain. Legion Sliver... it's good, giving +1/+1 for other slivers to all of them, but I think that a 4th or 3rd of another sliver would be better.
I was thinking of Bonescythe or Bonesplitter, and thought that splitter would be better, thinking on the worst position, having just 1 or 2 slivers in play, I would prefer a +2/+0 to a double-strike, more if their are 1/1.
I really needed a removal, 4 at least to get rid of huge creatures, such Wurmcoil Engine.
Also I'm thinking of adding Frenzy Sliver, as an aggro deck, that can avoid much creatures thanks to Galerider Sliver, giving an extra +1/+0 would deal much more damage, and synergizes very well with Leeching Sliver, but I would need to know what to take out, may that double-strike sliver.
I've had great experience using Firewake Sliver and Cautery Sliver against Wurmcoil Engine. Declare a sliver as blocker and sac it. No life gained, and you get in a point of damage. Also nice to get some value against spot or mass removal.
Frenzy Sliver is also recommended. I play 2 in my deck, and it usually works as an extra lord.
One more thing about sliver decks in general. I've seen many decks with maindeck Syphon Sliver. Unless your local meta is infested with burn and aggro decks, I don't see the point in playng Syphon Sliver maindeck. You are the aggressor in most games and gaining life is not a priority, dealing damage is. Having 3 in the sideobard however is probably a good call.
Where I play, there are at least 3 Scapeshift decks, and 2 o 3 burn. May again scapeshift could be out of maindeck, because I could go more fast, but when turn 4 for oponent reaches, it always do: crypctic command, next turn cryptic command, and if it doesn't have still scapeshift, snapcaster crypctic again, so there are 3 turns without making damage. So any damage+gain life will be very useful in the first 3-4 turns.
Also I'm thinking of adding Frenzy Sliver, as an aggro deck, that can avoid much creatures thanks to Galerider Sliver, giving an extra +1/+0 would deal much more damage, and synergizes very well with Leeching Sliver, but I would need to know what to take out, may that double-strike sliver.
In my opinion, you are losing a lot of potential with 4 of some slivers.
For example, 4 Two-headed Sliver, 4 Striking Sliver... you have more chances to draw more than one, and you lose spots that other slivers can fit much better. Because having in field 2 first strike or 2 can't be blocked except by two or more is a bit useless.
Homing sliver it's another good card. Fetching another sliver can give you a boost with Aether Vial in field. I'll take a look on what to change to add 2 of it.
I run 4 mana slivers because 8, in my opinion, are exesive, yes, it helps to run more slivers, but with lands and vial it's enough fast, for me atleast.
Also, if you want more high-cost mana, you can run to 6 mana and put that one that gives +3/+3 to all your slivers, Megantic Sliver.
A friend told me to add Gemstone Mine too, so, with Reflecting Pool it's an extra card to have colored mana for non-creature spells, mostly for the sideboard, and may add Mark of Asylum, and avoid lots of burning cards that targets our pretty slivers. Also this works perfectly with other cards, witch will you put into sideboard?
I just play one Venom Sliver, just in case I play with other deck that may play Tarmos, Oothe... and huge creatures. If not, it's sideboarded because it will become almost an useless sliver.
Edit: after some games, with just 2 Urborgs, I didn't like it much, Leeching is a good card thought, but sedge is not. Gonna go for another thing, like Venom Sliver again
Mmmm, I'm thinking to put a couple of Kira's in the sideboard, that will also help a lot against UWR control, burn... with all that removal and burn to all my Slivers. I played one now agains UWR control, and it was an easy 2-0 for it.
Also, I changed the list from above with 2 Gemhide and 2 Manaweft, so two slots available, and thought of Bonesplitter Sliver and Virulent Sliver, so now there are 4 mana generator instead of 6, giving place to a more aggresive creatures.
Well, sometimes, when the match it's getting hard, with huge creatures against you, is that you can't get rid of them, such with a Path to exile, or even a Vapor Snag, because of the lack of colored mana for no-creature spells. Another very important thing, is that if they put a Blood Moon on the battlefield, if you don't control an Aether Vial, game it's over.
So that is why I was thinking on sideboard, and so far I found 3 Sliver cards that can go very well, let's see them:
Harmonic Sliver - Great card to destroy thouse enchantments like Blood Moon (must have a Vial or Gemhide Sliver or Manaweft Sliver) Necrotic Sliver - A great card too for Blood Moon if you have it on battlefield. Also, will be a good pick against Pyromancer Ascension, Valakut, the Molten Pinnacle, and cards that can be very awful against slivers. Ghostflame Sliver - Affinity it's a very hard match, if you can put this into play, you do a lot of things against it, because Etched Champion could be blocked, and even destroyed with one of both cards from above.
I added 3 of each Slivers mentionen above. What you think of it? What else I could add to sideboard?
I will check thouse cards also for the sideboard.
I was thinking of Bonescythe or Bonesplitter, and thought that splitter would be better, thinking on the worst position, having just 1 or 2 slivers in play, I would prefer a +2/+0 to a double-strike, more if their are 1/1.

Tell me your impressions from the deck, and specially the sideboard
Where I play, there are at least 3 Scapeshift decks, and 2 o 3 burn. May again scapeshift could be out of maindeck, because I could go more fast, but when turn 4 for oponent reaches, it always do: crypctic command, next turn cryptic command, and if it doesn't have still scapeshift, snapcaster crypctic again, so there are 3 turns without making damage. So any damage+gain life will be very useful in the first 3-4 turns.
Also I'm thinking of adding Frenzy Sliver, as an aggro deck, that can avoid much creatures thanks to Galerider Sliver, giving an extra +1/+0 would deal much more damage, and synergizes very well with Leeching Sliver, but I would need to know what to take out, may that double-strike sliver.
My list so far is the following:
4 Sliver Hive
4 Ancient Ziggurat
2 Gemstone mine
2 Reflecting Pool
2 Mutavault
2 City of Brass
4 Aether Vial
1 Bonescythe Sliver
1 Bonesplitter Sliver
3 Diffusion Sliver
1 Firewake Sliver
3 Galerider Sliver
2 Gemhide Sliver
4 Leeching Sliver
2 Manaweft Sliver
4 Predatory Sliver
1 Sidewinder Sliver
4 Sinew Sliver
1 Sliver Hivelord
1 Sliver Legion
2 Spined Sliver
2 Striking Sliver
2 Syphon Sliver
1 Two-Headed Sliver
Sideboard it's still on work, but have think something with these cards, and hope you can help with it!
1 Harmonic Sliver
1 Necrotic Sliver
1 Kira, Great Glass-Spinner
1 Leyline of Sanctity
1 Mark of Asylum
Of this sb, I think the most strongest are Leyline, Mark and Kira, and a very good potential of necrotic, that can beat up a lot of permanents.
For example, 4 Two-headed Sliver, 4 Striking Sliver... you have more chances to draw more than one, and you lose spots that other slivers can fit much better. Because having in field 2 first strike or 2 can't be blocked except by two or more is a bit useless.
I run 4 mana slivers because 8, in my opinion, are exesive, yes, it helps to run more slivers, but with lands and vial it's enough fast, for me atleast.
Also, if you want more high-cost mana, you can run to 6 mana and put that one that gives +3/+3 to all your slivers, Megantic Sliver.
even without much creatures producing mana, with Aether Vial you can still put your creatures from hand into play! but that is not for modern o.O
Gonna test the new slivers!
Edit: after some games, with just 2 Urborgs, I didn't like it much, Leeching is a good card thought, but sedge is not. Gonna go for another thing, like Venom Sliver again
Also, I changed the list from above with 2 Gemhide and 2 Manaweft, so two slots available, and thought of Bonesplitter Sliver and Virulent Sliver, so now there are 4 mana generator instead of 6, giving place to a more aggresive creatures.
So the deck for the moment looks like this:
4 Cavern of Souls
4 Sliver Hive
3 Reflecting Pool
3 Ancient Ziggurat
2 City of Brass
2 Mutavault
2 Urborg, Tomb of Yawgmoth
Artifacts:
4 Aether Vial
Creatures:
4 Predatory Sliver
4 Sinew Sliver
2 Sedge Sliver
2 Gemhide Sliver
2 Manaweft Sliver
1 Sliver Legion
3 Diffusion Sliver
3 Leeching Sliver
2 Galerider Sliver
2 Spined Sliver
2 Striking Sliver
2 Syphon Sliver
1 Bonescythe Sliver
1 Blur Sliver
1 Firewake Sliver
1 Sidewinder Sliver
1 Two-Headed Sliver
1 Bonesplitter Sliver
3 Necrotic Sliver
3 Ghostflame Sliver
3 Harmonic Sliver
2 Kira, Great Glass-Spinner
So that is why I was thinking on sideboard, and so far I found 3 Sliver cards that can go very well, let's see them:
Harmonic Sliver - Great card to destroy thouse enchantments like Blood Moon (must have a Vial or Gemhide Sliver or Manaweft Sliver)

I added 3 of each Slivers mentionen above. What you think of it? What else I could add to sideboard?
