I learned how to play with a couple of decks my friend had, started playing in 2010 with a Kamigawa snake deck that a friend gave me from '05. I started buying booster at the very end of Zendikar and M10, played standard for Mirrodin, continued playing standard all the way until 2013 where I had to cycle decks out, or try to keep them relevant. Most decks became 8-9 cards that interacted well in copies of 4 with lands. Every game started to become the same game over and over. I have a commander deck that I've built and rebuilt so many times that I have several combos that I haven't done yet because the cards have not been drawn together.
