there is a mechanic that Scott Anderson was using in one of his sets called Muster that could be a very useful in that it rewards tribal deck building but is sufficiently broad in ts wording that it can be used in many different tribes. He hasn't been active in a while but I'm sure if someone reached out to him it would be fine.
Also @The-DM I really like your Sentry card, very nice. Only problem is it really should have flying, people will assume it has flying because it has wings, could potentially cause issues in gameplay.
