-Ditto's access to Imposter makes it have a nice niche on the metagame,as a revenge killer with Choice Scarf
-Relaxed nature and 0 Speed IVs are used to make Ditto the slowest as possible for the case of a Ditto vs Ditto scenario,while also providing bulk to tank opposing Ditto's struggle,while 248 HP makes the way easier for Ditto to switch-in on Hazard stacking teams.
-Ditto can also opt out for an specific IV spread to makes it's Hidden Power ground-type when transformed,which helps against opposing Manectrics and Electric-types in general.
