Looking for first pic and offering last 2 (read description plz)

So I know my LF has more valuable stuff than my offering, I’m quite aware I will not get everything there for what I’m offering. I’m mostly expanding my options to possibly get at least a couple.

I have two shiny Necrozma’s, both with Wormhole Background. I have two shiny Kyogre’s, one with the Wild background. My shiny celesteela is in a pokeball from the special researches.

I also have a bunch of other regular non-shiny backgrounds, including Kyogre, Groudon, Palkia, and Dialga with the Wild background. I have Nihilego, Necrozma, Celesteela, and Xurkitree with the Wormhole Background. I have all the comm day pokemon with backgrounds, along with the Lapras, Elekid, and Ponyta costumes with the team backgrounds. Finally, I have a regular GMAX Toxtricity (lowkey) with the Wild background.

For the latias, I’m mainly looking for either a mirror or a swap for a latios, as I got unlucky with a floor lvl shiny.

For the gmax gengar, I’m mainly looking to swap that for my Toxtricity (lowkey form) and if possible as a lucky for usability (and the wow factor of having a shiny gmax/mega).

For the Nihilego, I’m mainly looking to swap that for my Pokeball Celesteela (with the Nihi in either a pokeball or Ultraball).

For the Bunneary/Lopunny line, costumes are preferred but I’d take a regular shiny for a mega evolution. I’ve had poor luck these past few days with raids for them.

Shuppet/Banette is in the same boat, I’d prefer a usable mega evolution variant.

I also have a larger list of more general shinies that I didn’t think needed to be included. If you want to see that, pm me.
