I'm looking for cards to build my UWr control and UW Tron in modern. Below are the things I am looking for:

UW Tron
Celestial Colonnade x3
Batterskull x1
Ghostly Prison x1 Champions of Kamigawa
Pact of Negation x1
Thirst for Knowledge x1 MM
Seachrome Coast x1

UWr
Steam Vents x1
Tectonic Edge x1
Cryptic Command x3
Vendilion Clique x1
Ajani Vengeant x2

Gr Tron
Pyroclasm x4 Full Art Textless

I am hoping to build the UW Tron first, so items from that have more of a priority. Below are some of the bigger items I have to trade, of course you can always check out my tradelist:

Kaalia of the Vast Consecrated Sphinx Gisela, Blade of Goldnight Oracle of Mul Daya Tariel, Reckoner of Souls Grave Titan Temple of Enlightenment

I updated the original post with what I still need.
