The whole reason why I joined MTGCS, make a good custom set with good, creative people (and I'm the boss:) ). So pretty much:
RED: fire tempered men who make great warriors
GREEN: Children of the forests who make a lot out of a little
BLUE: Mysterious people who use the waters to cover up plans
I don't have any cards yet, but with your help, we can make a set to rival WoTC!
This bit here will change to say what the current project is:
good ideas for this: maps, card drafts, lore and stories, anything to base the cards around.
(Can we try to add in some sort of DoT damage?)
EDIT: the rulers/deities are being made.
