>>49867061Zacian mainly because its too optimizrd. Mega- Ray is more versatility but it technically has the SLOW FRAIL MIXED ATTACKER spread, its just that it has the raw base stats
Meanwhile Zaican is just disgustingly optimized. It has box legendary stats with a minmaxed stat spread for Fast Physical attack and an ability that increase its attack even more. And its Movepool might not be as good as MegaRay, its still amazing and has all the moves it needs to take care 99% of the game.
To add insult, Steel/Fairy is one of the best Defensive typing's in the game so in the rare instance it doesn't OHKO what's infront of it, it can take whatever hits it needs.
The only thing in the game that could check (not even counter/just check) Zacian was Unaware Quagsire because it ignored the Intreped sword boost).
Meanwhile Zamazenta is so useless it's only viable in OU (but its stats are just a bit too high for OU to hand so its stuck in in nomans land of being a shitty Uber).
