My friend and I do a lot of normal battles. What I want to know is if I bring a fully trained Pokémon except in levels (let's say level 7 Blissey) when it changes the level to 50, will it still add in all the IV's and EV's as if it was level 50?
When I say changes to 50, I mean when the battle is starting and every Pokémon has its level set to 50, whether it's above or below.
Yes, EVs and IVs will be considered when the Pokémon is auto-levelled to 50.
