>>20245039If there were 30 or 40 mons with a power level around Aegislash, Lando-I, Thundurus-I, and CharX's power level, it wouldn't be a problem and that would be the new OU. But if you look up into ubers, most things even with low viability eclipse the power of everything I just listed, so there isn't a lot to pull from there, and there isn't a lot in the current OU that can play ball with the stuff I listed and the stuff that's been banned, so that theoretical full power creep OU couldn't exist yet.
They're right to ban things that are obviously broken. Aegislash isn't obviously broken, but it is mechanically and statistically more effective than almost anything else in OU.
