I don't care where. I love Magic. I have giant collection. I have about 10 decks right now, but I'm always tearing them apart and rebuilding them, or at least retooling them.
I once had a swamp/plains life building deck that was banned from competition because it was deemed very unfair. I had an enchantment or an artifact (can't remember the name) that absorbed all damage from my opponents via counters, then allowed me to remove all counters from it, so that I could just keep using it and never get hit. Pissed some people off.
