Suicune

Suicune is one of the prominent wincons of the tier. With a great defensive typing in Water and a high base HP stat, Suicune can set up on most bulky Pokemon in the tier. After one Calm Mind, Suicune is tough to revenge kill, as it deters physical attackers from switching in due to a potential burn from Scald, and special attackers have to break past the Special Defense boosts from Calm Mind. Pressure is an excellent ability on Suicune, as it allows Suicune to PP stall opposing Pokemon. Suicune's reliance on Leftovers leaves it vulnerable to Knock Off users, especially Cyclizar, as it is crippled for the rest of the game upon losing its Leftovers. Despite having a solid base Speed stat of 85, it is still slower than some common threats such as Mimikyu, Jirachi, and Cyclizar. Faster Pokemon like Galarian Zapdos, Krookodile, and Gengar can exploit Suicune's lower Speed and hinder its progress-making or sweeping opportunities.
