What might make more sense is a "past standard" brawl several years into the future. Like 5 years from now we could have a 2015-2016 standard brawl, so TGT + whatever two expansions this year (and the adventures). Good way to make people waste dust on cards that haven't been relevant in quite a while.
Yeah, I actually also thought of that, or something similar in the distant future. I'd have nothing against it, but given the outrage after the current brawl not being inclusive I can see how such brawl would tick ppl off :P
