Buying some pokemon

[Cephot]

I'm trying to buy a few pokemon, Gengar, Aegislash, Greninja and Yanmega. I don't really have much to spend or trade but I have 10 pcs that I will give.

Hi, i can help you get a Greninja and a Gengar and i can also give you a Duoblade but i don't really know if giving 10 pc for those pokemon is allowed.
Because the lowest price allowed is 20 pc

I forgot to mention that I don't want any of them custom, just random nature, ivs, nothing matters
