Amoonguss

Amoonguss should be the first Pokemon under consideration when redirection is required, as it's often the best suited for it. Likewise, its low Speed and access to Spore make it valuable when Trick Room support, or a counter to Trick Room, is needed. Regenerator is an excellent ability for keeping Amoonguss healthy throughout battles, although it's comparably not as strong as it has been in previous years as a result of a more offensive metagame making switches more punishing. It also has excellent natural defenses which, when combined with resistances to common types such as Fairy and Water, generally allow it to take hits very well. However, its typing is a double-edged sword, as it also causes Amoonguss to be weak against Fire and Flying, which creates issues against common foes such as Primal Groudon and Mega Rayquaza. Furthermore, while Spore is a great move, preparing against Smeargle's Dark Void is so common that it inadvertently hurts Amoonguss's ability to put foes to sleep, as well-constructed teams are generally prepared against status. You should also be aware that Amoonguss is almost entirely a team player, as it lacks offensive presence despite Grass Knot's often high Base Power. It should also be ensured that Amoonguss is not outclassed on a specific team by other redirectors such as Togekiss and Clefairy, which might situationally be more appropriate picks.
