I highly suggest that people have a look at what other engines such as Firemox, MTGForge, and Incantus do. These guys have worked on their engines for years/months, and when you work on a MTG game, at one moment or another you'll run into the problems they've already faced. LOTS of useful information on these games' blogs/forums/irc channels
