Is that you I'm trading with?
If it is, just a tip for next time you want to evolve via trade; line up everything in one line, and then just go down the line, going to the start for the original tradeover from the other person. To evolve three Pokémon would take four trades, whereas sending mine back and forth over and over makes it take six (and gives it a migrane LOL). Typically anything I trade goes to Box 31, right next to my party where the cursor begins. I used the Relicanth in this case as it's a hard to catch fish, and I had just bred some today for a challenge. It also clears that Dex entry in case you don't need it yourself. :)
