As part of our continuing commitment to monitoring developments in the metagame, the PvP Coordinators have noticed that Kyurem is quite possibly a presence that is overcentralizing, difficult to prepare for, and perhaps too strong for our current available answers. This belief is reflected in our recent Viability Rankings update, where Kyurem is now in S-tier.
We highly encourage you to participate in this discussion and offer opposing viewpoints, as we recognize that any discussion within a small group of relatively similar people is liable to produce the same ideas, regardless of their competence. We are especially interested in hearing your thoughts on Kyurem's role in the current metagame. Have you had difficulty handling it with your current team? Has it invalidated any builds you wanted to try? Or, on the other hand, are you having success utilizing it?
While Kyurem has several viable sets, including Choice Specs and Choice Scarf, we believe it is at its most dangerous when running Substitute, Roost, and Freeze-Dry. On Gold server, players tend to prefer the fourth move Earth Power, while on Silver, players also favor Toxic. This set is able to safely create Substitutes on a vast majority of the viable defensive Pokémon in the PRO metagame, especially balance staples such as Tangrowth and Rotom-Wash. Its titanic base HP stat permits it to easily reach 405 maximum HP, thereby creating 101 HP Substitutes which Seismic Toss Chansey cannot break. Ferrothorn, despite a nominal type advantage, is simply run out of Gyro Ball due to Pressure, while even something like Eviolite Bisharp is faced with the possibility of a straight 2HKO from Earth Power as well as both Substitute and Roost, denying Sucker Punch. Against offensive teams, the combination of Freeze-Dry, Earth Power, and Kyurem's natural bulk forces switches to no end, which it can easily set Substitute on, guaranteeing that it claims a kill shortly thereafter.
However, Kyurem's weakness to Stealth Rock and the relative speed of the metagame do somewhat hold it back. Mega Lopunny teams tend to play at a pace that does not often let Kyurem enter the field, while Mega Scizor is one of very few immediately safe defensive answers (though, in an extended interaction, it can certainly eventually get frozen or worn down by hazards). Mega Metagross immediately threatens Kyurem with its faster speed and massive power but simply cannot come in on Kyurem using Substitute more than once. Slowking, which is rapidly gaining popularity, is both a good teammate for Kyurem and a form of counterplay. With Future Sight, it can ensure that a teammate safely enters the field to face a Kyurem without a Substitute while barely dodging the 2HKO from Freeze-Dry. Ultimately, Kyurem is sometimes manageable in battle, even when it poses extreme strain on the teambuilder.
We will take into account all feedback we receive before the end of the season, when we intend to make a final decision. Well-constructed and defended reasonings will naturally be given more weight, but we do care even if your opinion is simply that you like the Pokémon. At this time, there are no other Pokémon or combinations that are immediately on our radar, but we will keep you updated as soon as possible if that changes.
