I wouldn't see a problem with promoting matches, both official and Rumble over on Twitter. It can not only get more people interested, but also get people to participate in the CBUB as well with more character submissions and fights as well as maybe Draft matches again in the future. Especially since there are a ton of people that really wanna look for something other than Death Battle to quench their crossover fighting thirst, wether it be waiting for another episode/season or just thinks the show has gone down hill.
