When I first started playing magic, I started with white. Very conservative very careful. I remember I had opponents sweating since everyone else was so agro they couldn't figure me out and those not playing agro were trying to do the all-artifact-lock-thingy.
Then I start to play fast red. "Its better to burn out than fade away." Just to try to outrace time spiral.
Then I played true blue, bounce you too.
When masticore came out I toyed with a colorless/mana building deck.
Just because.
Then I stopped playing. I still have some of the cards, I just couldn't bring myself to sell them.
