Best Magic the Gathering Deck?

I haven't played Magic in a good.... 6 or 7 years and want to get back into it. I'd like to know what decks are good, and get a few people's inputs as to which decks will win tournaments. My skills in CCGs are unmatched locally and regionally (I've won many chicago and madison area Yugioh and Yu Yu Hakusho tournaments in my day), so I just need the deck to match the skill.

List your suggestions below, starting with color/theme, deck build and why they're good.

This isn't a troll or joke either, I seriously want to get back into Magic and have just enough money to do so.

 

Depends what format you want to play.
If you want to play Legacy I'd go any kind of Storm Combo deck. I don't really play Standard or Extended so can't help you on those formats.
If your skills are really that good you should go draft, it's the most skill intense format in the game easily. And you don't need a deck to play.
