>>41719094>they don't, they want the "powerful" moveset for their starters (as in, 2/3 STAB moves for monotypes, 3 for dual types and some random coverage move). Bibarel is for the shit moves like Strength, Rock Smash and CutPrecisely the point. Empoleon doesn't learn a move stronger than Surf until 59, at which point they're extremely likely to be at the league and have no business learning it. Same for Waterfall.
Which leaves you with Cut, Defog, Rock Smash, Strength and Rock Climb that they can all fit in the team.
