Well for what it's worth, when he was trading, I gave him somewhere around 30+ monsters for the stuff he traded me. Also, all clones of this Gengar were traded to me by cjlaborde2nd himself at the time he traded me said Gengar, so that I could trade them without sending them to a cloner. Lastly, that event Gengar doesn't have 3 flawless IVs in 3 random stats like your Celebi did, thus it was harder to reset for a flawless Hidden Power; the fact that you can trade it to your friends is just bonus.
1) Even if it was harder to reset for it, you didn't do it.
2) resetting is tough for anyone. To try to belittle any reset is insulting.
3) If it was so easy logically this forum should be full of hidden power fire Celebis right? AFAIK this is the first one on smogon rn. You should know it's not easy since you tried resetting for a hidden power fire Xerneas and settled for a flawed one.
4) someone actually offered me the same Gengar for free trying to beat you to the punch.
