Y'know what, special challenge time.
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.
