Hey, Ironica! I definitely like your idea. I think it will benefit new players (like myself) in getting started with the game.
My response to your strategies and ideas on special abilities:
I like this idea if you want these decks to be used for training only. If you want some decks that newbies can start out playing in tourneys with, special abilities need to be included. But perhaps you could expand on this idea and post a new topic on starter tourney decks. But I do like this idea very much for training.
My response to your strategies and ideas on offense and defense:
Great. Just fantastic. I've heard that the blue/silver combination is quite strong in offense. For your defense in deck 1, I have a question: what were your strategies on the gold/red combination? I would very much like to here so I can a. improve and b. offer criticism on the deck. As far as deck 2 goes, gray and brown are very strong because banding is common with these brigades. If you have no special abilities, you want to be able to band for sure. Also I like your ideas with green/purple so as to help banding capabilities. Also in deck 1 you want silver and blue cards that are capable of banding. But you probably were thinking of that already.
Overall I love the idea and encourage it greatly.
God bless,
