So every starter can hit the other two super-effectively!
This idea of each hitting each other super effectively was already done by the sinnoh starters. (Empoleon can hit Torterra with Ice Beam, the others are self-explanatory).
And ENOUGH with the Fire/Fighting pokemon. They're getting stale fast.
Having a move that can hit the type is not the same as being a type that is SE against it. --- "As I was walking up the stairs, I met a man who wasn't there, he wasn't there again today, i wish I wish he'd go away."
