I'd like to throw this out to any and all rumbles when doing these matches.
try to grab a character that hasn't been used to much and post it here.
If your having difficulty, We have many awesome artists and writers that frequent these boards and ask them of their capabilities based on our standard lines and see what we come up with.
that way we learn about other characters and/or comics we might overlook, and we have fun seeing what they are capable of. :)
