The following lists of moves are considered "Potentially Competitive" in the general OU metagame. These are the moves with sufficient Base Power and/or secondary effects that make them viable in the metagame IN GENERAL. That does NOT mean that these moves are automatically considered to be competitively viable on every pokemon with access to the move. Ultimately, the circumstances of an individual pokemon will determine if a move is Competitive or Non-Competitive. But, any move not on this list is probably not a competitively viable move, and would be considered "extra" or "flavor" for a full movepool.
These lists should be consulted when the Topic Leader assembles the move list in the OP of the Attacking and Non-Attacking Move Discussion threads. Topic Leaders can pick moves from this list, and have reasonable assurance that they aren't overlooking any "good moves".
