I actually like the concept of this deck. It actually does make sense to me. You flip hostility, and cast a board sweeper. Right there you're looking 6 to the face from hasted hostility, that leaves 14 damage needed after that's onyl 5 damage from spells, for letal damage! I would say, screw Gaea's blessing: You need
Volcanic Spray!
Main Combo: 14-cards
4 Oath of Druids
2 Hostility
4 Sensie's Top
3 Crop Rotation
2 Fork
1 Wheel of Fortune
1 Regrowth
Sweepers: 8-cards
2 Cave In / Pyroclasm (if you find you don't have the red cards to pitch)

4 Forbidden Orchard
4 Wooded Foothills
1 Windswept Heath
3 Tiaga
3 Mountain
2 Forest
2 Great Furnace
4 Chrome Mox
1 Lotus Petal
=================================
So as I said before, the main plan is to in one turn:
1) Oath
2) Boardsweep
3) "Deal" 5 damage to your opponent
4) Swing for 21
A few things that got added:
~ Chrome Mox. This will be a big boon when it comes to exicuting your plan early.
~ More artifacts, including Great Furnace (and crop rotate for great furnace) for...
~ Shrapnel Blast. this gets the 5 done in one pop. Swing for 15 anyone?
~ Fork. This deck could definately benefit from fork on neumerous spells. Its actually fairly easy to beat someone with Price of Progress forked! Even without Hostility.
I think in a slow enough, "aggro" budget meta you could own face with something like this.
You might consider running something like Sneak Attack in the sideboard, and put the extra hostilitys or other big creatures in the sideboard.
Anyway good luck with it.
