As it stands there is no easy way to search through (or ban from certain tour formats e.g. metronome) the list of illegal Pokemon, such as eternal floette, missingno, and the pokestar studios props. I would prefer if this were an option such that these Pokemon could be both easily displayed as a group without going to the teambuilder and easily removed from custom game/metronome tournaments. These are the only group of Pokemon that lack these features.
