So I am starting to look into making a competative deck.  I would like to make an extended and standard.  But I want to start with Extended... So with that in mind, im looking to find a good combo deck that works.  As far as color goes I was thinking White, Green and either Blue or Red.  Whats good in tournments?  I will be playing in local shops.  But despite the location of my play, i want something I can win with... dont we all? =P  But anyways, any help would be appreciated.  some combo ideas, maybe some breakdowns of what a deck would have (a general description would be nice, or even a list)  that way I have something to base a deck off of or alter it to my likeing. 
~Thanks
