Guildmage

Guildmage (Visual)

All the Guildmages in a single deck, with ways of generating tons of mana (e.g. Mana Echoes), and helper cards like Training Grounds.
I tried to make each of the Guildmages have something to do (e.g. I put in cheap instants/sorceries for Izzet Guildmage).
I use Sliver Queen to help generate tons of mana (the tokens can be used with Earthcraft or whatever). There is a fair amount of potential for this deck to go infinite, so be warned if you find that sort of thing distasteful.
