Quick Powder doubles Ditto's speed right? which would be 428 maxed? (the analysis says 418).
Also, Has anyone tested the exact stats that ditto has after transforming? I know Ditto keeps its own HP but I've been getting conflicting answers on the other stats.
Of the things i've heard....
1. Ditto copies every stat point the opponent has (with exception to HP) exactly as the opponent has it.
2. Ditto copies only the base stat setup for that pokemon essentially making it like an untrained version of the foe.
3. Ditto takes the base stats of the foe and applies its own EVs to said stats, essentially making it a trained version of the foe.
Are either of those correct or is there something different?
Well, since the max. Speed Ditto can attain with +Nature and 252 EVs is 214, then yes, Quick Powder would make that 428.
As for Ditto's Transform, here's what we've got in the D/P Analyses Move Descriptions for Transform:
[NAME]
Transform
[SHORT DESC]
Transforms into the foe.
[LONG DESC]
Transforms into the target, copying its stats (except HP), moves (at 5 PP each), type, and ability. The stats are copied exactly, so EVs, IVs, and level are irrelevant. IVs of the target are copied for purposes of Hidden Power, as well. Metal Powder and Speed Powder's boosts are lost upon Transforming. Choice Band, Choice Scarf, and Choice Specs keep their boost upon Transforming.
Does that help?
