Bumping for MisterJH

Could anyone list some staples for the different monocolors? Im trying to be thrifty and still win something at fnms to make it worthwhile

I would go with RDW. It typically has a turn 4 win and most of the prices have gone down due to {Hellrider} being in a duel deck and cards like {Stromkirk Noble} and {Ash Zealot} in event decks. You could go into more expensive territory with {Thundermaw Hellkite} and {Boros Reckoner} but my deck worked fine without them.

Out of all of them? White Weenies is perfect to buy low on. You can get {Elite Inquisitor}. {Champion of the Parish}, {Boros Elite}, {Gather the Townsfolk}, {Silverblade Paladin}, {Thalia, Guardian of Thraben} at ultimately low prices.

I don't know enough about RDW to comment.
I know about Green Flash because I've beaten it a billion times, but it does look like fun and puts up a fight.
