Nice, but I feel like you have some Slivers that just do the same thing, I believe you have three that gives flying, two that games the ability to tap for mana and a few that only gives +1/+1 or such. I have nevered played or against Slivers but I pretty sure, there are other cards that you can use instead of ones that you already have that gives flying or such already in the deck.

kiddrangon thank you for the input. I agree that there are duplication's of some ability's. Over the years i have found that some of the ability's you need to duplicate in my playgroup. Unfortunately in my playgroup I run into a fair amount of removal and graveyard hate. It is also not uncommon for me to play my commander 4/5 times or more in a game.

Understandable, every playgroup is different.
