Springtide Storm is there.So I take it the Hisuian Starters do have signature moves, if I can foster a guess
H-Decidueye's signature move is likely Triple Arrows.
H-Typhlosion's signature move is likely Infernal Parade.
H-Samurott's signature move is likely Ceaseless Edge.
And Tornadus's signature move is Bleakwind Storm.
Thundurus's signature move is Wildbolt Storm.
Landorus's signature move is Sandsear Storm.
And Enamorus's is likely Take Heart?
Just my guesses.
