Lost pokemon?

I was doing holon quests to build a new team but to do so I had to beat Prof. Maple cause I wanted delta larvesta/volcarona. I saved and closed the game, turned off my computer, etc. The next time I loaded insurgence up they were gone. I.E. I went to put D. torchic on my team but it wasn’t in the PC. Idk if anything else disappeared but that’s one I definitely noticed. I went back to the pyramid and everything but nada. How do I get D. Torchic now?

If you want, I could hatch an egg and send you one. Just give whatever you want in return. I’ll need to know your trade name.

My trading name is CoolBreeze. I never traded before so what do I do?
