@Cha_Fey_S is a scammer. she said she would train my and to 4 hearts each. she says she can't do it and demands 200k pds. she trained 1 of them to 1 heart and now she isn't giving the pokemon back.
to improve upon the discord idea, when you choose what rarity u want to trade, there could be a chance that it trades with a lower/higher rarity, that way the excitement will remain and it'll be fair too, like lottery.
i'd like you to train please, i have been looking for a heart trainer. i already have 2 hearts on my greninja i need 2 more on it, i also have 2 other greninjas with 1 heart each so please train them as well. as for the price i can pay 1 million pokedollars.
greninja is a dark type immunity and is immune to psychic type pokemon,
this post by patrick contains a few training accounts (one for each type) , Typedark <--- (click this link to train greninja or any other dark type)
