I disagree on the comment that you need 4 vises to make it good. While obviously 4 is a lot better, even with 1 when you do draw it, its just as effective, you just don't draw it very often. Chimeric Idol is a good threat and its hard to get rid of. Also, if your mana base can support it, Flametongue Kavu is excellent.
I agree that Black Vise is good (heck, it was on the Restricted List for a while) and has some synergy with Wheel of Fortune. Just keep the Wheel; there's a reason it's still on the Restricted List
I run both the Sprites and the Baloon Brigade in my RG cheapo deck... it almost guarantees you a first round flier - and sometimes you don't even need him to fly...
With a cheap deck, one R isn't going to kill you...
The Kird Ape is almost as good, except it's always a target and never flies in R/G.
Put it this way, would you rather have a Scryb Sprite or no flyer first round? With 4 1 drop fliers you aren't always going to get that first round flier, but 8 ups the odds... The biggest problem these cheap decks have is sustainability. If the game gets to a point where your opponent gets going you find yourself running out of bullets quickly.
