I've never actually seen custom tabards or griffins used before in a Brikwars army
I appreciate the compliment.
One of the difficulties with medieval/low tech brikwars is that battles can become attrition wars. You know, throw men with swords at men with swords. This is all fine and good and makes for a good time of brick-carnage, but the game progresses slower than, say, combat with rockets, explosives, or lasers.
To fill in these "high damage" roles that inherently speed up gameplay (and look nice), I think most medieval brikwars generals ought to seriously consider using siege weapons, wizards, magical creatures, and the like. These we consequently lead to better photo ops, more carnage, nice MOCs, and that little extra oomph
