Magic clone

So, I was reading this old post from mtgrares, where he says he'd like to create his own TCG:

So I did some thinking. Er, quite a bit of it actually, so let me summarise it in bullet-point style to get right to the point(s).Ideally I could create my own TCG so I could "computerize" it and sell it for $5 or $10. Obviously I have no idea how to really create my own TCG. Wizards says that only publish 1% of all of the cards created for a set, which means that many cards never see the light of day. I think it would be cool to mash together Magic's and Marvel/DC VS rules into one game. I don't really know would this be legal but if I stole the same ideas from both games, the resulting TCG would be vastly different from either game.
- 1. I think it's possible to create a game with rules fully compatible with Magic, ie, a Magic clone. That way your players wouldn't have to learn a whole ruleset from the start. The problem would be to avoid litigation. Three ways I can think to do this:
- 1a. Stay off the IP (intellectual property, ie mana symbols, character names etc).
- 1b. Keep your central server on European ground ('cause you can't trademark rules in the EU).
- 1c. Release for free and as open-source. That would be a bit like the open-source folks do, where they create free versions of proprietary software (say, Open Office). Being free I think makes it easier to claim fair use (I may be very wrong on that!).
- 1d. Create a radically different format, ie something that isn't really a collectible card game but something else altogether. This really is the bit that can take most of the wind out of the patent lawyers' sails.
- 1a. Stay off the IP (intellectual property, ie mana symbols, character names etc).
- 2. As to this radical new format, here's my Big Idea. Instead of publishing cards for players to collect, you could let them create the cards themselves. That would be a lot like scripting cards to add to Forge. Or of course some projects here, like mine, have parsers that let you add a card automatically to their engine using only its Oracle text. The more artsy types could also add their own illustrations.
The players could create their own cards, then upload them to the game's server for verification (to make sure they're compatible with the game's rules etc) then they could put their cards in a deck and play that deck against others online. Or they could play against an AI opponent of course.
A central body, like the DCI, could maintain the ruleset and add new mechanics, so the game could keep growing. They could also enforce some power-level constraints (so there would be no 20-damage-for-0-mana spells ^_^). And create some "base" sets also, to get things started.
So basically, I'm talking about a free and open source Magic clone that can be played only with virtual cards, created by the players themselves. Sound like fun?
