When you need prices or tix, who do you call?

Does this look familiar to anyone?

Foil Vendilion Clique [PRM]                        102                
Foil Birds of Paradise [PRM]                       105   
Foil Emeria Angel [PRM]                            108                
Foil Wrath of God [PRM]                            123                
Foil Vindicate [PRM]                               126                
Foil Voidslime [PRM]                               126                
Foil Orim's Chant [PRM]                            126                
Foil Maze of Ith [PRM]                             132                
Foil Cryptic Command [PRM]                    255 

If you go to http://supernovabots.com/ , you can find a nice price guide for your foily needs and you know what you can cash in for tix.

I currently have set my eyes on this:

Foil Lion's Eye Diamond [MI]                       165       186

which means it's bought at 165 and sold at 186.

Since I don't really use my foil promo Maze of Ith much, I might wanna cash it in and get funds for a foil Lion's Eye Diamond (mainly because I can't find a seller for the normal one yet).
(I wonder what I would trade for a foil Black Lotus next time...)

I hope that I figure out what I can do against workshops because mana light decks have a really tough time against spheres unless they have Mana Drains and big planeswalkers. Need to stop wandering away from the problem at hand...
