>>51090967OU council are the ones who use overlooked strategies. There was an OU council member who won a big tourney using Mega Glalie back in S/M. A completely unheard of Pokemon, and he brought it into vogue. High ladder OU players have been the trend setters. Hail has been popular for the first time ever in this generation because a high ladder player brought a Hail Balance team to #4 in OU ladder with Vanilluxe as the Hail lead. This is after Crown Tundra, too, because his team also had Swampert and Cinderace.
Also, the council very rarely quickbans anything. Usually bans are put up to a vote for high ladder players. That's the fairest method, since if you have the skill to get the reqs, your input is more valid than the rabble. You have to have the knowledge, wherewithal, and execution to be one of the around 120 - 150 people who make it into the suspect test voting phase.
