All that really matters is playing the game - THAT's the way to keep it alive.
As much fun as a PC would be, it would really serve no purpose other than dividing the already small player base - "I think standard should be these cards" "no, I think we should ban all cards after
Mount Doom" "no, I think we should let ALL cards be legal".
Trust me on this - just play the game. Put up posters at local game shops and introduce the game to new people. Exposure is key here. I put up a poster at my local shop and didn't hear anything for a full year, but then I got a couple emails about it out of the blue, and now we've got plans to get together at least monthly to play. I'm positive that just by being in the shop we'll get more people interested in the game, and then BAM, we've got ourselves a local play group big enough to hold tournaments.
A time may come when there is a real need for a PC, but it isn't now. Just find another player, agree on some house rules, and PLAY.
