I got it after about 690 more Timburr battled. Another female but I named it Plank anyways. This one will evolve. I caught it in my second heal Ball. Atleast I'm getting these in under 1,000 now.

I already have Shiny Conkeldurr because of a raid battle so I don't need it. So that line is done. I named that Concrete lol

It kind of sucks that it wasn't a male but I don't care. I'm not going to continue to just try and get a male.

May go for Galarian Meowth
Another Shiny Milcery just to keep as a Milcery
Go for other sizes of  shiny Pumpkaboo and Gourgeist
Female Espurr to evolve into Female Meowstic
Swirlix
Scraggy
Rufflet
Or the longest and probably the hardest Hunt Shiny Authentic Sinistea

Which one should I go for next?

I will be finishing the original Pokémon Sword and Shield Shiny Dex before thinking about buying the Sword DLC.
