The Best Possible Sliver Deck. (Legacy)

Description
Sliver aggro at its finest. All 1-2 CMC Slivers with AEther Vial to toss them onto the battlefield ASAP. With 12 Slivers that give +1/+1, this becomes the ultimate Lord deck!

The Deck

1 CMC: 15

3x Galerider Sliver - Running 3 because I want this ability every game. It doesn't stack, so I can't run 4, but this card needs to be hitting the battlefield.

4x Sidewinder Sliver - Half of a Sliver Lord for 1 mana. Makes them much more aggressive. Either they block and he counts as a faux-sliver lord, or they don't and you just convinced them to let you through to their HP.

2x Striking Sliver - First strike is powerful. That being said, I never want to draw into 2 of these guys because the ability does not stack. 2 of these is the right number.

4x AEther Vial - This card is a 4 of out of necessity. The speed and consistency that this card brings to this deck, or any hasty aggro deck, makes this card irreplacable.

2 CMC: 23

3x Heart Sliver - This guy makes an impact when he hits the board. Especially if he's being thrown down with more than 1 Sliver during the same turn. I want to run into this card most games, which is why it's a 3x instead of 2x, however a non-stacking ability does not warrent a 4x in any Sliver deck.

4x Manaweft Sliver - A bit better than Gemhide Sliver in the mirror matchup, but otherwise a staple that needs to be a 4 of for mana consistency and ramp.

12x Sliver Lord - Muscle Sliver, Predatory Sliver, Sinew Sliver. These guys are the heart of this deck. 12x Lords is powerful in any tribal deck, but slivers really know how to pull it together. All 12 are necessary to make this deck as powerful as possible.

4x Leeching Sliver is sort of a pseudo Sliver lord. After some play testing, I found this card to be a serious threat.

2x Crystalline Sliver - Shroud is shroud is shroud. Very helpful, can side in two more against targeted removal heavy decks.

5 CMC: 2

2x Sliver Legion - If this guy can successfully hit the board and you have 2-3 other Slivers on the board, then you have basically just won the game. The amount of power this creatuer adds to your Sliver horde is absolutely astonishing. Much more board presence than Sliver Queen or Sliver Overlord.

Sideboard:

2x Crystalline Sliver - Helpful to side in against decks with heavy amounts of targeted removal.

2x Grafdigger's Cage - This guy is obviously for some graveyard hate.

3x Harmonic Sliver - Helpful to remove pesky enchantments and artifacts.

2x Necrotic Sliver - For when Harmonic Sliver isn't enough. Can hit any permanent, including lands, which can help deal some damage to combo decks. Also great at planeswalker removal.

2x Sliver Hivelord - For those jerks who like to run Supreme Verdict or Wrath of God. F those guys.

2x Stony Silence - Anti-artifact side.

2x Swan Song - This one is a side for 2 particular cards, but can also be a useful side against almost anything. But this card is primarily to counter a turn 3 Blood Moon or Back to Basics because those 2 cards can just wreck me from the get go if I don't have AEther Vial or Manaweft Sliver on the battlefield. Easiest way that I've found to deal with those cards.

I love criticism, so if you have any please make it constructive and help me make this deck as good as possible!
