>>54595624Chien-Pao has a higher effective BST than Darkrai, Shaymin-Sky, and Deoxys thanks to its ability. It barely has less effective Attack than Deoxys-A while not being made of paper and having an immunity that lets it switch in.
Kyurem-B and Kyurem-W have 20 less BST than Arceus and Kyurem-B wasn't banned until Gen 8 gave it Dragon Dance.
Baxcalibur wasn't broken until it got Scale Shot in Teal Mask, and what pushed it over the edge is that it was only checked by Dondozo thanks to burn immunity and incredible defenses behind screens. It's possibly the psuedo-legendary that got the most buffed after its introduction behind only Kommo-o. It's also the psuedo-legendary with the best ability. Thermal Exchange is even better than Salamence's Intimidate and Hydreigon's Levitate.
Calyrex-Ice has two abilities, one of the strongest signature moves in the game, and BST higher than Kyogre and Groudon, and even still it's never seen in Ubers even as its other form got banned. It's barely got more usage in Ubers than Ribombee, and it has less than Palafin and Annihilape. By all acounts, if it were an actually good type it'd be at the top of Ubers. Ground/Psychic, Water/Psychic, even Bug/Psychic would push it way up.
