Time Dilation
Status, 5 PP probably, Psychic-type I guess?
Basically, it only activates while Gravity is up. As long as Gravity stays up and the user stays in, time will keep speeding up for everything except for the other Pokémon and for Gravity and Time Dilation themselves, with time getting 1 turn faster every turn.
Now, there’s a huge “wtf” factor here, I get that; in other words, the turn after Time Dilation is used, time starts going to 2 turns per turn; the next turn, it’s 3 turns per turn, then 4 per turn, and so on and so forth.
Yes, even though a turn is a turn, you can’t say it’s more than one, “turns per turn” means that end-of-turn effects activate multiple times during the turn. Because the user of Time Dilation also goes faster- the other Pokémon do(es) not- the user uses its selected move multiple times in one turn.
So, to explain this better, here’s an example of an interaction with no Time Dilation in effect:
>Alakazam uses Shadow Ball
>Hits once, one chance to lower Sp. Def
>Wailord holding Grip Claw uses Whirlpool
>Hits once, Alakazam hurt by Whirlpool once, will stay in Whirlpool for 4 more turns
With Time Dilation in effect, once a speed of 3 turns per turn is reached:
>Alakazam uses Shadow Ball
>Hits thrice, three separate chances to lower Sp. Def
>Wailord holding Grip Claw somehow tanks this and uses Whirlpool
>Hits once, Alakazam hurt by Whirlpool thrice, will stay in Whirlpool for 2 more turns
Honestly, the one part of this I’d love the most is to see the user have Toxic used on it and watch as the move backfires horribly.
Learnset includes a few of the Pokémon that learn Gravity- almost only the actual Psychic-types and Dialga- and Celebi.. Or make it Stantler’s signature move
TL;DR: Move you use during Gravity and now Gravity also makes time faster but the other mons don’t move faster so you get to use a bunch of extra moves
TL;DR TL;DR: It’s MiH.
