Since some people have been confused as to what the Metronome tier rules are, here you go: All Pokémon must have Metronome and only Metronome. The move, not the item. All Pokémon must be holding a Leppa Berry, if any item. Some notes: Ubers are allowed. They are not banned from the Metronome tier. A complete list of those who can lean Metronome can be found here. There you go: the Metronome tier rules. Have fun!
