>>31864044Total Defense in Pokemon is a product of HP and the relevant Defensive stat, while Total Attack is a product of the Attacking stat and the move's base power. Rotom-A isn't bulkier than Jirachi, and you don't use the sum of the two stats because Blissey has way worse Physical bulk than Aggron. Using just the base stats and assuming our sky snek is using Dragon Ascent, Mega Fug would have 21600 Atk and 10500 Def.
