I recall that there was a Counter the Pokemon project where the community build teams of Pokemon to counter each other. Once the teams are built, then the teams will be used by well-known players. Granted, the last time it was done, the battle wasn't able to be carried out due to some reasons (although the project had been done successively several times before).
Now that the ORAS metagame is more or less settled (and the SPL has ended) , would it be the right time to once again kick-start this project?
