Hello there !
Some time back I thought about building Sliver deck but I never found out how the deck could work. The problem is that 5cc goodstuff or 5cc zoo will almost always be better than 5cc sliver deck. Why ? Because every card of that deck makes something on its own and is better than almost any creature in your deck. Slivers are dangerous in numbers but they dont have enough protection mechanisms to get things going. They have Crystalline Sliver that you need badly to protect your slivers from spot removal but there is no way you always have him when you need him (that is why I own 12 of them). Then Wrath effects completly ruin your day and it is very difficult for you to get back to the game. I see you have some kind of reanimation element in your deck but I don't see it working when you really need it.
Also the problem about sliver deck is that slivers don't have exact strategy and they are just too random. They can't be used as aggro deck cause they dont work for that plan. You mentioned that you want sliver control deck. Well, for me there is no way these two words work together. Slivers can't control your oponent in any way. Sliver deck is kind of swarm deck but it works only in legacy formats where you have 4 of each sliver you need, all of them are cc 2 so you can use your vial every time and you have counterspell backup. In highlander it is damn hard to build a deck like this especially for the reason why highlander is unique – there can be only one.
For better understanding I give you an example for what I mean. Compare following cards on their own:
Winged Sliver – Cloud of Fearies, Augury Owl, Floodbringer, Spellstutter Sprite
Muscle Sliver – Wild Mongrel, Kavu Predator, Nest Invader, Scavening Ooze
When you have both of them in play you have 2x 2/2 creature with flying.
When someone is playing red, for 3 mana, he plays Fire Imp and kills your Muscle Sliver and has 2 power on the ground against your power in the air. Respectivelly he can kill your flyer and still have 2/1 ground unit able to block your muscle man.
I could give you similar example for each color probably.
I give you another example:
Your first 4 turns look like this:
Round 1: Plated Sliver (2/3, trample, lifelink)
Round 2: Muscle Sliver (2/3, trample, lifelink)
Round 3: Horned Sliver (3/4, trample, lifelink)
Round 4: Essence Sliver (4/5, trample, lifelink)
When your opponent does nothing till his round 5 (say he went first so he is not completly crippled) you did 2+4+7 (gained 7 life in the process) = 13 damage
Now lets say your oponent plays Shriekmaw. Suddenly you dont have your 4/5 beater. You have 7 damage worth of creatures and your oponent can still block your Muscle Sliver to humiliate your army even more and he is still not dying because your 7 damage are exactly necessary to kill him.
In red color your oponent can play Flametongue Kavu. He cant kill your lifelink hero and instead he kills your Muscle Sliver. Next Round you can do 6 damage which is not even enough to kill your oponent and he can block your Essence Sliver and you will have 1/2 trample and 2/3 trample retards.
I especially dont mention non-creature spells because in that case you would be screwed without a way of going back.
Everything I want to say is that slivers are only good in numbers and they suck big time on their own. When your oponent plays at least competetive highlander deck, you usually have very little chance of winning with creature spells.
I am not saying you shouldn't play sliver deck. I am just saying why I consider it very hard to build consistently and effectively.
I wish someone will give you good advice how to build sliver deck cause I am curious myself if this deck really might work.
I also have to mention that Birthing Pod is really great card. But how great it is, that much it sucks in Sliver deck. Guess why. If you can't I tell you it is because it kills your man and gives you NO advantage since you terribly need that man who is , sadly, in your graveyard now.
And by the way, you are missing one of the best slivers in the deck – Chameleon Colossus.
