Copied deck idea from chrisrazor-- though I made major changes in card selection, mostly due to my lower budget and my liking for "clean" decklists.
The basic strategy is to stall until you have 4 defenders, one of which has to be Axbane Guardian, and a galvanic alchemist. You can then tap the Axbane to get 4 mana, untap him for 3, rinse, and repeat. Once you have an indefinite amount of mana, use Sands of Delirium or Doorkeeper to mill the opponent out.
Think twice + divination help the combo to go off faster, while the large amount of defenders, and the fogs help keep you alive.
Evolving wilds and Gatecreeper vines help mana fix.
Negates and Dispels are to keep your creatures alive, and to counter your opponent's counters.
21 lands due to the Gatecreepers, the very low avg. mana cost, and the fact that axbane can function as a very efficient mana source. Too much mana has killed me more often than too little at 22 lands.
Sideboard is to deal with wipes (especially that uncounterable Supreme Verdect) and heavy control decks.
I'm pretty happy with this deck; I think it's competitiveness to cost ratio is great. I'd appreciate feedback on my selection of counterspells and defenders.
