So the same can be said for Gallade, you can use sableye as the lower tier check (which is way more useful than sap sipper), every priority user except for some fighting types can be effective, scarf users are also able to kill Gallade after he takes some hit, not to mention whether mons like kabutops, hurricane kingdra and Scizor. To be honest sub glare Serperior have way less checks, maybe he also deserves a ban? π±
