Sigh First of all, us Mods can read deleted messages, but in this case, I'll forgive the snide remark you left at the end there.
I was asking about this for two good reasons. 1 I wanted to make sure you, as a new user to the site, were not trying to scam someone who didn't know better.
2 If you were being genuine about wanting to trade, you could always have meant a Galarian Zigzagoon from Gen 8 wanting to trade it for something only available in Gen 9. I for one have done trades like this before, and although they require a good deal of trust on the part of both parties, can generally lead to success.
