Greninja

Greninja

Thanks to Greninja's great Speed, diverse movepool, and access to Protean, it's one of the premier offensive threats in the CAP metagame, being capable of pressuring offensive and bulky teams alike. This also gives it the freedom to pick its checks and counters. It also has access to Spikes, and thanks to its wide movepool, it's capable of pressuring Tornadus-T, the most common Defogger in the metagame, only adding to the overall pressure it exerts. However, Greninja is really frail and easy to wear down between entry hazards and Life Orb recoil. In addition to this, Greninja suffers from mild four-moveslot syndrome, as it can't always fit all the coverage it wants. Despite its great Speed, it's still outsped by offensive Pokemon like Mega Alakazam and Tapu Koko as well as Choice Scarf users like Kitsunoh and Volkraken, so it can be picked off quite easily.

Ash-Greninja

Ash-Greninja's decent offensive typing coupled with high Special Attack and Speed lets it take on many common Pokemon such as Landorus-T, Mega Crucibelle, Colossoil, and Mega Latios. It also has access to Water Shuriken, which lets it threaten faster Pokemon as well as Trick Room teams and is a decent STAB move post-Battle Bond, and Spikes. It's rather weak before transformation, however, meaning it needs to KO something to become threatening and may experience trouble breaking past Pokemon such as Ferrothorn and Krilowatt early-game. Additionally, the prevalance of bulky Grass- and Water-types such as Jumbao, Tangrowth, Arghonaut, and Toxapex can make it hard for Greninja to get a KO. Greninja is also frail, which may make it hard to switch into play.
