Zamazenta

When one first sees Zamazenta's well-rounded stats, it may look like an excellent Choice item user; however, Zamazenta is unfortunately hindered by a poor typing and an even worse movepool. Despite having several serviceable coverage moves, Zamazenta can't piece them together in any threatening combination. Therefore, it can't consistently break through defensive cores using common Pokemon such as Ho-Oh, Necrozma-DM, and Zygarde-C. Zamazenta's STAB Close Combat also has low PP, which common physical walls such as Xerneas, Zygarde-C, Necrozma-DM, and Eternatus easily exploit. Despite Dauntless Shield and high stats, Zamazenta is paradoxically fragile and struggles to find defensive utility. Lacking reliable recovery or other support options, it cannot take repeated hits from common physical attackers such as Zekrom, Groudon, and Marshadow. Other Choice item users such as Dracovish, Calyrex-I, and Urshifu-S should be considered long before Zamazenta.
