Umbreon

Umbreon provides tremendous value as a specially defensive wall that can support its teammates through Wish passing and status spreading. Umbreon is most often utilized in Wish passing to some of the tier's best Choice item wallbreakers such as Galarian Zapdos, Hisuian Goodra, and Basculegion-F. Similarly, Umbreon can prop up balance and bulky offense structures by comfortably tanking attacks from special wallbreakers like Basculegion-F and Gengar and spreading status while maintaining its own health with Moonlight and Wish. Umbreon is efficient in neutralizing setup sweepers because of its natural bulk and ability to use their strength against them with Foul Play. Umbreon is, however, severely allergic to Bug- and Fighting-type attacks, which are commonplace in a metagame with strong threats that can force it out like Galarian Zapdos, Mienshao, and Terrakion. Using Terastallization on Umbreon grants it several key benefits, notably Tera Poison to flip the weaknesses to Bug and Fighting and become immune to poison. This, however, is not enough to help it break through important checks to Umbreon like Krookodile, Hisuian Goodra, and Registeel.
