>>22700237>Never be OU with its current movepoolYou're right. Mega Pidgeot is a decent Pokemon and perfectly usable in battle, but it is a lackluster Mega and not worth using in high-level competitive play unless you like it.
However, the stats and ability give it a niche niche that it performs quite well. Even without an item, its high base power STAB hits hard. With possible future movepool changes, it always has room to improve. A status move, strong coverage, or another powerful STAB would go a long way towards boosting its effectiveness.
