Shiny Ditto Trainer
Nope, it gives 4 Speed EVs per battle. For example, with Power Anklet equipped:
Blitzle yields 1 Speed EV (Natural) + 4 Speed EVs = 5 Speed EVs
Lillipup yields 1 Attack EV (Natural) + 4 Speed EVs = 1 Attack EV and 4 Speed EVs
These results is doubled by Pokérus:
Blitzle with Pokérus yields 2 Speed EVs (Natural) + 8 Speed EVs = 10 Speed EVs
Lillipup with Pokérus yields 2 Attack EVs (Natural) + 8 Speed EVs = 2 Attack EVs and 8 Speed EVs
If you want to get 4x the EV from fighting a target Pokémon, your Pokémon must have Pokérus and Macho Brace equipped. But usually this is less efficient compared to a Pokérus and Power [Item].
Great Response. Appreciate it.
