Also, comparing psueod-legendaries and normal mons, a pseudo-legendary versus a final-stager generally has a 40 attributes vs 35 attribute points as a difference. Add in Ace for both of them, and 45 vs 40 is literally an 11% difference. A visible edge, but far from insurmountable, which fits for how simpler I'll be doing things and how certain mons are hyped up as especially stunning.
While Dark Lady is an energy-absorbing bitch with a cheating barrier. Then for offense she's basically magical artillery.
