Well, after playing Gun for awhile and pronouncing it good, I'm deciding to rework the old U/G/w aggro deck I posted awhile back with the horrible mana base. Since I'm poor, no power for me; feel free to add Ancestral and Time Walk to taste.
4x Nimble Mongoose
4x Savannah Lions
4x Blurred Mongoose
4x Meddling Mage
2x Call of the Herd
4x Force of Will
4x Brainstorm
2x Impulse
4x Tithe
2x Misdirection
2x Mana Leak
1x Sylvan Library
1x Windfall
4x Tundra
4x Tropical Island
4x Savannah
4x Mishra's Factory
4x City of Brass
2x Forest
Sideboard:
4x Swords to Plowshares
4x Samite Ministration
3x Blue Elemental Blast
4x Wax/Wane
Why not grow?
It really is grow without the Dryad, who has this nasty habit of getting sucked into the Abyss and/or dying on the spot. I like how the Mongoose is untargetable and uncounterable, if a little small on the toughness scale. If you want, replace the Blurred Mongoose with Quirion Dryad.
There's only two Calls of the Herd for two reasons. I only own two and there really isn't a need for many more than one 3/3 on the table at the time. Anurid Brushhopper may just be outstanding in that slot however; I'm really liking the way it screws with Balance.
As usual, any threats on my life (and critiques of the deck) are appreciated.
I'll kill you good!!
Seriously though, you dont have enough blue cards(18) to run SIX pitch counters, i would cut the two MisD for two more Mana Leaks or Impulses.
