U/R deck focusing on the Prowess mechanic. Prowess creatures, most with flying, and lots of instants both for creature removal and counter-spelling, and prowess triggers. Looking to figure out exactly which creatures to focus on, and maybe get some card draw.

I'd like to future proof this deck a bit for DTK expansion, so avoid Theros block unless it provides a significant advantage. Also, I'd rather not spend a lot of money on a casual deck.

Any input would be appreciated.
