Nihilego

Nihilego's base 103 Speed stat allows it to outspeed common foes such as Mega Charizard Y and Kyurem-B with ease, which, when paired with Beast Boost, gives Nihilego the ability to quickly get out of hand. This, combined with a unique offensive typing and an excellent Special Attack stat, lets it function as an anti-metagame breaker that excels at dismantling Mega Charizard Y balance teams along with other bulkier control-oriented teams containing Pokemon such as Incineroar, Zapdos, and Tapu Fini. Despite these upsides, Nihilego may find itself struggling to pick up KOs due to the presence of many specially defensive Pokemon in the format. Furthermore, Nihilego is also easily forced out by Steel-types and strong physical attackers, as it is very frail.
