Thank you for all the suggestions and the reasoning behind them. I may make a new deck that is a more optimist version of this with a bigger budget, but I will say that for most of your suggestions that will really impact the deck are pricey. They are effective, but still wallet slayers. Also, on the Start your Engines, the fact it gives all your creatures, including both the vehicles and pilots +2/+0 for a final swing.
I made a similar deck today as well. Mine is green white, but it is the same idea. Great minds think alike. If you want to look at mine, here is the link: http://www.mtgvault.com/silverrock75/decks/face-pummeler/
The only reason Sky Sovereign is in there is because I already had 2.
This is a budget deck that I currently run. Half a playset would double the price of this deck. ~$40 is nice and cheap. I largely avoid $75+ decks so 80 is over, and 120 (a full playset implemented) is not my style.
I have now posted and I'll look at those cards later.
