Umbreon

Umbreon's great bulk allows it to take on both physical attackers like Zeraora, Landorus-T, and Mega Metagross and special attackers like Meloetta, Primarina, and non-Taunt Tapu Lele, and its Dark typing makes it immune to Prankster from Pokemon like Whimsicott. Umbreon also has great utility moves like Charm and Moonlight that enable it to take on Mega Gyarados, Mega Charizard X, and Choice Scarf Haxorus. Furthermore, Umbreon can pressure setup Pokemon such as Landorus-T with Foul Play and prevent Tapu Lele from setting up Calm Mind with Snarl. However, Umbreon has trouble facing bulky Pokemon such as Porygon2, Magearna, and Z-Move Togekiss, which are able to take its attacks and stall out of Moonlight's PP. It also suffers against common Leech Seed users such as Serperior, Jumpluff, and Mega Venusaur because of its inability to do major damage to them and its limited recovery with Moonlight. It further suffers against Taunt users such as Deoxys-S, Tapu Fini, and Kommo-o, as it cuts off Umbreon's recovery options and allows them to either stall it out or take it out with their super effective attacks.
