My friend is working on a 4 or 5 color Green deck for Mirrodin T2, since that is the kind of deck he enjoys to play. Back in the day, it went something like Birds-Grainger Guildmage-Maro-Quirion Ranger-Tradewind Rider-Armageddon. We are still unsure of the skeleton, but right now it is Birds, Vine Trellis, Maro. Other possibilities include Forgotten Ancient or Hunted Wumpus, though I like Forgotten Ancient the best. We have ruled out White as a potential color. If you play white, then you play Exalted Angel, or maybe Savannah Lions, but we feel it would be best to stick with GURB. Here's a rough decklist for us to work with: GURB - Mirrodin Type 2 Creatures (24) 4 Birds of Paradise 4 Vine Trellis 4 Forgotten Ancient 3 Ravenous Baloth 2 Nantuko Vigilante 2 Hystrodon 3 Goblin Sharpshooter 1 Phyrexian Plaguelord 1 Kamahl, Fist of Krosa Spells (14) 4 Mana Leak 4 Dark Banishing 4 Plow Under 2 Oversold Cemetery Land (22) 4 City of Brass 1 Wooded Foothills 1 Bloodstained Mire 1 Polluted Delta 6 Forest 2 Swamp 1 Island 1 Mountain // not sure about the land base just yet There are some other things to think about, like cycling Decree of Annihilation as an instant Armageddon. Of course Mirroding may fill out the deck, but let's work on what we've got right now! Also...playing 4 colors might avoid all the gross color hosers in 8th.
