Celesteela

Celesteela is quite bulky and possesses a solid defensive typing that provides it with a decent matchup against a large portion of the metagame. With Beast Boost, Celesteela has the makings to become even bulkier and thus annoying to take out, forcing the opponent to focus their attention on its removal. Although Steel is generally seen as a poor offensive typing, the influx of Fairy-types in the metagame and Celesteela's 999kg weight make Heavy Slam surprisingly reliable as its sole attack. Sadly, Celesteela struggles tremendously with opposing Electric-types and the incredibly popular Fire-types and falls flat against most opposing Substitute users due to its reliance on Leech Seed. This sometimes leaves Celesteela as a detriment to its team's ability to maintain momentum, though other times it serves as a late-game wincon by wearing down various threats while passively recovering health.
