first of all:
DRAGON SCALES, and pkmns like:
KINGDRA
magmortar/electivire(it would be cool if they r poketopia)
any shiny
legends(specially events)
event pokemons
Porygon-Z
and rare pkmns like that
then maybe some other random evo items like:
magmarizer/electrizer
reaper cloth/protector
dawn stones
no tms(exept swagger(twice))
i think thats all, but if u can think of any other thing post it or only choose sth
or say no thks
