The chest UR actually did go up in power at one point, from 12 to 13. Noreen, Ghede, Erebus and I think 1 or 2 after that were very efficient PWR 12. And as always, each one that comes out has slightly more attack than the previous. Then it seems that they reach a point when it's in danger of the atk/pwr ratio surpassing the high-tier cards that usually get sold in card packs, so they bump the power up and nerf the ratio.

I think I'll do some research and see what the last card was before they raised the PWR to 13 and then get the atk/pwr ratio of that card. My guess is that we can expect the chest UR to get bumped up to PWR 14 once the ratio of the PWR 13 meets that ratio.
