I gave 10 proteins, 10 carbons, then defeated a trainer with 6 magikarps, twice, using poweranklet + pokerus.
After that, I chained 15 shinxs with powerbracer + pokerus and one without.
I won a tentacruel with just pokerus.
Finally, I won 3 starlies with poweranklet + pokerus, and one with just pokerus.
That was my plan. This is what I did. I will give you your pokemon back, don't worry.
The only place where I may got it wrong was when I attached the power items. I attached the power items to my crobat + the taillow only had exp share and pokerus.
Accidentally, I may miss out giving an item in an occasion, which I don't remember.
It's a shame, because I tried to do it perfectly.
Give me 10 minutes, and I will be on wi-fi if you want!
