Effect: Deals damage to enemy Pokémon automatically upon their switching in. Although it is held back by its Normal typing, (however, a Rapid Spin equivalent without any immunities would be beyond broken and would annihilate stall as a playstyle) Rapid Spin is a powerful support move that many teams would not function without, which secures it a spot at #10. In fact, Rapid Spin is so useful that many Pokémon, such as Volcarona, Gyarados, and Salamence, almost necessitate Rapid Spin support to function effectively. Rapid Spin almost singelhandedly ensures that stall isn't the most dominating playstyle in every tier, let alone OU. Luckily, Rapid Spin stops your Pokémon from taking obscene amounts of damage every time they switch in. Hazards are everywhere in OU Ferrothorn, Skarmory, Forretress, Tentacruel, and countless Stealth Rock users are just waiting to litter your side of the field with endless obstacles to your Pokémon. Notable Users: Starmie, Donphan, Forretress, Tentacruel
If the target of this move is a Ghost-type, then the move will fail to have an effect. It also removes Leech Seed from the user.

However, there are some moves that are so excellent (they have great Base Power, utility, or other great effects) that a Pokémon that has at least one of these moves is almost a necessity on a respectable player's team. Many Pokémon actually rely on certain rare moves to remain viable in OU Breloom has Spore, Cloyster has Shell Smash, and Scizor has Bullet Punch. While it may not be as important as typing, if a Pokémon doesn't have the moves, it probably isn't going to be OU. A Pokémon's movepool is one of the main factors that decide its viability.
