So what are the tournament rules?
Let me copy pasta it...
Pokemon Diamond/Pearl/Platinum Tournament rules:
1v1, 6 pokemon format
No Uber tier Pokemon allowed
Species clause (No more than 1 copy of a single pokemon species per team. Variations of the same pokemon are no exception.)
Evasion ban (Moves that increase your evasion are not allowed: Double Team and Minimize)
Sleep clause (You may not put more than 1 of your opponent's pokemon to sleep at a time. If they use rest on one or more of their pokemon, you can still put 1 of their pokemon to sleep)
Freeze clause (Although there's no way to enforce this mid game, you're not allowed to freeze more than 1 of your opponent's pokemon)
OHKO ban (straight forward, no OHKO moves like Guillotine, Fissure, Horn Drill, or Sheer Cold)
We will likely use self-KO clause (If you use Explosion or Self-destruct with your last pokemon to KO your opponent's, you lose. Destiny Bond will not give you the win if this results in both players losing all of their pokemon.)
Event moves are allowed, but keep in mind that we know what pokemon can get what moves.
No R4 or other emulators allowed, real copies of Pokemon only.
No hacked or edited Pokemon.
No changing teams in between matches; you must use the team that you present to us.
You must present your team at the time of registration for inspection. If known to you, please present IVs and EVs with your team.
We will have IV calculators on us and we will be well informed on the legal movesets of most, if not all, Pokemon.
Please arrive at least 1 hour prior to the official start time. We would like ample time to inspect everyone's teams.
Prize: To be revealed
edit::
Please keep in mind that until Nintendo officially releases the Rotom secret key, Rotom alternate forms are banned from this tournament.
We will be using the Smogon.com rulings on which pokemon are uber/OU/UU/NU as of this edit. Further smogon rulings will be ignored for Fanime.
UBER Pokemon:
Arceus
Darkrai
Deoxys
Deoxys-A
Deoxys-D
Deoxys-S
Dialga
Garchomp
Giratina
Groudon
Ho-oh
Kyogre
Latios
Lugia
Manaphy
Mew
Mewtwo
Palkia
Rayquaza
Wobbuffet
Wynaut
If it's not on this list, it's allowed for the tournament. There is a Soul Dew ban for those using Latias.
I'm thinking of banning rotom alternate forms even if they release the key. People are starting to breed their teems already and if the rotom key is released 2-3 weeks before fanime nobody will be able to adapt in time.
