Y'know what, special challenge time. (also, Its_A_Random and I need a ref.)
The Restaurant at the End of the Universe
Ah, Milliway's, the Restaurant at the End of the Universe. A fantastic  place, where you can buy anything to eat you want, at any price thanks  to the magic of millions of years of interest and the amazing powers of  Bistromathics. As you enjoy whatever three-course-meal floats your boat,  you notice a rival a few tables across. The end of the universe  spectacle isn't going to be for another hour, so why not enjoy a small  Pokemon fight?
Of course, it seems you've committed the ultimate blunder in the  Restaurant-you've managed to meet yourself, both a past copy and a  future copy. You remember your embarrassment at seeing your other two  selves for the first time. And now you're back, this time as your  current copy. You can feel the raw embarrassment radiating from your  future copy, who has just arrived a third time at the same general area.
Your rival appears to be in the exact same predicament-his future and past selves have arrived at the same general area as well.
There's a Pokemon arena conveniently unused in this copy of the  universe...and you can distinctly remember having a Pokemon battle there  with your rival when you were younger. Your future self seems to have  long anticipated this.
"9v9" Triples, technically 3v3 Triples with three iterations of each mon.
3 days DQ
12 chills per Pokemon, 4 recoveries per Pokemon (and by Pokemon I mean all three copies of that Pokemon.)
Arena: The Restaurant at the End of the Universe
A futuristic restaurant with plenty of neo-neon and exotic plastic  plants. There's a round dirt arena of about 50 feet diameter to fight  in, with several fountains around the arena to call on for a water  source. The scents of the cuisines of 42 million cultures permeate the  air. All moves permitted.
The twist of this fight is that a past version and a future version of yourself have also joined in the fight.
-Your past self uses the version of each mon you enter when it first got  approved, with the present form's nature. Use the search function if  you can't find it.
-Your present self will send out the current version of your mon.
-Your future self will send out a version of your Pokemon that is at  maximum evolution, with all moves and Dream World ability unlocked.
Due to a quirk in spacetime, nobody knows who is going to win or lose  this match, despite having participated in it already. Time travel is a  dick. For the purposes of damage, each Pokemon counts as a separate  entity, and any combination of past, present, and future Pokemon can be  used at any one time.
Counters for both the referee and the battlers are at the discretion of a head ref.  Because of this, it is recommended Flora or Deck take this one. Other  refs can take this, though-Flora/Deck assign counters, however. PM  the ref the original copy of each mon from the prize claiming thread  (or, if it's a starter, from your profile's starred moves), the current  version from your profile, and the future version, based on the current  version.
Smeargle can Sketch ANY moves utilized and has access to EVERY move in  the future state, but can only take permanent Sketch slots from moves it  has traced from past or present pokemon only. Past Smeargle only gets  its starting Sketch moves and cannot permanently Sketch moves gained  here.
Starting evolution is also banned, as making the rules any longer than  they already are would cause brain implosions. Items, if used, would be  from the present trainer only.
