Forge Source and a new CCG-Game, Re-posted

The moderator told me I should post on the Forge forum as well 
So here goes, I'll post the original topic link here:
http://www.slightlymagic.net/forum/viewtopic.php?t=5966
Tl;dr
Where can I get the Forge Source and Do you guys have any tip, tricks when making an own TCG that has cards that essentially alters the rules of the game? I'm currently gathering information before designing and programming my own TCG ( Though not Magic, or as advance as magic ).
Kind regards Moonkis.
