Like in every metagame in Pokémon, there is a number of Pokémon which usually dominate the game. OU is the higher tier after Ubers, which means that every player has a very large verity of Pokémon to choose from. However, there are still Pokémon which are more common to see in OU than others. Keldeo, Heatran, Ferrothorn and Landorus-T are a few examples for overused Pokémon that almost everyone meets every battle. Other Pokémon such as Emboar and Smeargle, are very rare in the OU environment but still can be seen on many successful teams.
So why would they use such Pokémon and not a similar one with better abilities that is overused?
There are many reasons. One of them can be that the Pokémon they have chosen, works well against specific threat that really puts the team on pressure. Another reason can be the surprise factor similarly to the use of common Pokémon with original sets.
Have you ever include in your team an uncommon Pokémon with little to no usage in the metagame?
How did you manage to come up with it? Did it go well in the end?
Do you prefer using only common/used Pokémon ? Why?
