Not that I want to show my age or anything, but here are a few facts with regard to the MoM and MTG comments in this thread.
Magic the Gathering, created by Richard Garfield, came out in summer 1993. In fact there is a Global Event slated for July 26-27/2003 to celebrate the 10th Anniversary of its creation. If you would like to know more about this you can visit this page,

Richard however played Magic the Gathering during 1992. Of course this was during the card games development. Read the following:

Master of Magic, created by Steve Barcia, was released by Microprose in late September/early October 1994. The game actually was in development while Magic the Gathering was in its creation stage

MoM actually had a Microprose advertisement inside the box for MTG when the game was released. Yes I have the original game and all the included material, I'm looking at it now
In fact it states:
"Coming Soon for Your PC...
Magic the Gathering
The first interactive multiplayer computer game based on the award winning and top selling card game
Magic the Gathering!"
Of course it was quite some time before we saw MTG as a PC game and it wasn't Microprose
Wizards of the Coast is in Renton, Washington. SimTex, Steve Barcias company was located in Austin, Texas. So did MTG influence MoM ? Well only Mr. Barcia can answer that for sure. Interesting that Microprose was advertising Magic the Gathering for the PC though...
In case you don't know, Richard Garfield didn't join Wizards of the Coast full time until into 1994. If I recall around the time frame MoM was released.
More tidbits although these happened a few years after the games released:
Spectrum Holobyte owned Microprose when MoM was released. In 1997 Hasbro bought Wizards of the Coast. Not quite one year later Hasbro rescued,(bought) Spectrum Holobyte in 1998.
Curious about those inter-relationships ? Well this article might clear up a few things, it's also an interesting read in general.

Hasbro still owns Wizards of the Coast but effective January 2001, Infogrames Inc. acquired the video game unit of Hasbro-Interactive that published CD-Rom products and Games.

So whats Steve Barcia up to these days?
Well he can be found at Retro Studios, http://www.retrostudios.com/retro.htm
in Austin Texas,which Nintendo helped to fund in March of 1999. He just recently finished up Metroid Prime for the Nintendo. http://www.gamepro.com/index.html?/nintendo/gamecube/games/news/27167.shtml
What's Richard Garfield up to?
Hmm, well he's no longer with Wizzards of the Coast. He will still be a consultant on MTG though. If you were unaware of this follow the link: http://www.wizards.com/sideboard/article.asp?x=sb20010501a
Here is a link to a recent interview with him and an interesting blurp I clipped from it

UGO: You have a keen eye for creating game situations that can be used to drive opponents crazy. Call us crazy, but it seems that your style of game design could lend itself really well to a turn-based or real-time strategy PC game.
RG: I have been interested in such a project for a long time, but have had a tough time convincing publishers to go along with them. They are very interested in my ideas, but when it comes to actually paying for the development they typically balk, because the ideas don’t fit in a mold that is easily understood. I don’t necessarily blame them – the things that excite me game wise are bound to be high risk ventures. I will keep working on it though and someday I may be talking about such a strategy game.
Just a comment on what it would likely look like, I would make every effort to make it so that click speed wasn’t as important as strategy, and yet the game moved quickly. This should be very possible; consider speed chess. Speed chess is not a slow game, but no one loses because they couldn’t “click on their pawn fast enough”, At least rarely.

Lastly for those who are interested here's a brief history of Microprose:
