Semi-Random Theme Deck Generator
Posted: 23 Sep 2010, 11:43First discussed in the "shandalar clone" thread, now a reality for simple constructed games.
Here's my sample theme:
White.thm
Lands = 40%
. Basic Lands = 67%(40%)
. Special Lands = 33%(40%)
Core Cards = 35%
Support Cards = 25%
For a 60 card deck it works out like this:
16 Basic Land
8 Special Land
21 Core Cards
15 Support Cards
The code will need to be tweaked to fill the land slots if not enough (or no) special lands are defined. Also, it currently attempts an equal distribution of basic lands, without regard to the actual color weighting of the resulting cards. But this is just a first draft.
