OU Monotype Changing Tournament
Basically the rules are simple, it will be a 16 man tournament set in Gen VI. You have to create a full team based around a certain type for example Fire. All Pokémon in the team need to be at least part Fire.
Ditto is banned from competing against all types expect Normal. Mega Evolutions that aren't already banned are allowed, as long as they are in there respective type. You cannot use Mega Evolutions such as Mega Aggron in a Rock type team, regardless of it being a Steel/Rock type before Mega Evolving, since it loses it's secondary type when it Mega Evolves.

1st Round: Fire- 16 Participants

4th Round: Electric- 2 Participants
Types can be changed by a public vote.
