Slivers was also one of my very first decks when I started playing Magic back in Timespiral. Have you seen the recent lists that are running 4 Sedge Slivers as additional lords? It requires a change of the manabase to include black shocks in addition to 4 Cavern of Souls and 4 Sliver Hives, but giving your slivers the ability to regenerate is really nice.

One of the changes I would make to this deck would be to shave off 1 hivelord for an additional Diffusion Sliver, since the biggest weakness of slivers is against decks with plentiful removal. I'd also have the 4th one in the SB in place of Virulent Sliver. I'd also try and fit either a Dismember or some other type of removal into the 75 somewhere. I'm still working on getting a playset of AEther Vials myself, as I only have 2 and 4 would be optimal. Instead of having 2 basic forests, I'd run 1 forest and 1 plains since a Blood Moon can shut down this deck in a hurry. That way you'll always have a chance to cast a sideboarded Harmonic Sliver to get rid of one.

+1 for Slivers!

Have been considering adding the Sedge Sliver (though I only have 3) as a third lord (and definitely one card for the cut would be one of the Sliver Legions. But it does mean I actually have to think a bit harder about the mana base.

Would 4 AEther Vials be optimal? There are great benefits to having them out in the early game, but become a nuscience draw in the late game. It's something I'm not sure I know the answer to so I went with the 2 after trying 3.

Definitely agree that cutting a forest in place of a plains makes a lot more sense than 2x Forest.

Thanks for the suggestions!

Greetings!

I play a Sliver deck myself and maybe can provide some additional experience.

Would 4x AEther Vials be optimal? - Absolutely yes!

I had the exact same doubt about the card before I actually upped it to 4x. AEther Vial does 2 things for you. One is saving you mana. The other, more important thing is, that you NEED to use it for combat tricks in this deck, to change the numbers on the board. And flashing in a turn 4 or 5 Striking Sliver with a vial set on 1 can be super relevant. Another important way to dodge superfluous vials in the late game is Collected Company - You naturally filter out the stuff you don't need. That's why you also want 4x Collected Companys.

@sergiodelrio Greetings and thanks for the opinion.

I hadn't considered the natural filtering that Collected Company would provide. I definitely value AEther Vial's ability to throw tricks during combat, but I think I need to reconsider the number I have in the deck.

Until I actually own a 4th I can only up it to 3 at the moment though!

Think it's time for an updated decklist.
