Looking to Update Sliver EDH

[Agrus Kos, Enforcer of Truth]

Looking for these cards:
{Dormant Sliver}
{Sliver Legion}
{Sliver Queen}
{Synapse Sliver}
{Garruk, Caller of Beasts}
{Harsh Mercy}
{Patriarch's Bidding}

There will be M15 needs, but I will wait on those. Notabkes for trade include {Snapcaster Mage} and {Ancient Tomb}. Binder is a bit out of date.

I have a harsh mercy that was going to go into my sliver edh deck. I'll see if I need it or not and what else I may not need patriarchs bidding probably can't be spared, but I'll see. I am looking to get into modern/legacy so maybe we can work something out.
