Hmmmmm.... Red, Green, Blue, White, and Black...
I have played Magic on and off in real life, never actually buying my own deck, always short or long term borrowing my decks from friends. I know how to play somewhat well, though I constantly ask what certain abilities do and such, and I actually don't know how the turn order works. Basically a working knowledge. With the links to the rulebooks in the first post you provided though, I should be good
My first deck was R/G. It sucked to high heaven. I still loved playing regardless of my always losing though. Second deck was pure red, and could actually hold its own, though it wasn't really my style. Recently I was borrowing a snake deck a bunch (green) and had fun with it (mold adder is especially fun when you play against a black deck and two blue decks at the same time)
However, the deck I had the most fun with was a blue mermaid deck I put together at my best friends house for a MTG birthday party he held. I destroyed all contenders.
So, Blue it is
