Delphox @ Firium Z
EVs: 4 HP / 252 SpA / 252 Spe
- Calm Mind
- Fire Blast
- Grass Knot
Like all of the fire types already mentioned, Delphox is able to kill of both of these pokemon quite easily, while also offering defensive utility against this core. Delphox is able to use Xatu as set-up fodder in 1v1 situations due to its inability to touch Delphox. As well as this, Delphox is also able to sponge any neutral hit from Klinklang. It is also able to tank +1 return from full if Klinklang has already used up its z-move, and a +1 Corkscrew crash is a roll to kill Delphox from full, albeit a somewhat even one. Delphox doesn't need to utilise its z-move against any of these pokemon, which means it can be used to hit more bulkier threats or even for gaining a completely accurate Fire-STAB nuke. Klinklang gets OHKO'd from fire blast, while Xatu takes around 65-75% from a neutral fire blast, with a neutral Inferno Overdrive and a +1 Fire Blast, which is the same as a blaze boosted fire blast, all being able to OHKO Xatu from full.
