I wouldn't count on Normal being it's primary typing as evidence. The only Pokémon that have Normal as a secondary typing are the Helioptile and Pyroar lines; every other dual-type that happens to be Normal-type has Normal as their primary type - most notoriously, every normal/flying type.Also, I heard from some people that Drampa might be an evolution of Dunsparce. Given its Normal/Dragon typing (note that Dragon is the secondary typing) and its color scheme, I wouldn't be surprised.
