All Im trying to do is trade my kadabra and get it back but its hard to get anything going because im a noob at this.. i just want an alakazam..
I've used negotiations twice in order to fill my 'dex--both were very frustrating, and only one came through.
First I needed a torchic, but I had the other hoenn starters, so I changed my trainer card to "Want WATER? Give FIRE!" (or something like that), and, when the trade started, I would put up mudkip and treeko and show two happy faces and a sad face, indicating that I was happy with the starters I had, but sad that I didn't have a torchic. After zero luck with that (some people understood what I wanted but didn't have torchic, others, often with full boxes, just kept showing off their shinies), I rearranged seven of my boxes to spell "torchic" and repeated the same thing. After a good long while, somebody finally had a torchic, but wanted a legendary for it just to be mean. Stupid. I ended up getting it from one of my friends...
The second pokemon I needed was vullaby; I changed my card to "need POWER SWAP" (or something like that, again), and showed my rufflet and braviary, in hopes the other party would understand that I needed their Black Version counterparts. I had no luck for a while, but finally someone (who had shown off their shinies at the beginning) understood what I wanted and traded their vullaby for my braviary.
Moral: sometimes people who show off are helpful, sometimes not.
