Would anyone be able to lend me a hand with some event Pokemon?

I'm short Dusk Lycanroc, Marshadow, and Zeraora for my living dex. Also Melmetal but I don't have Let's Go or Sword and Shield, so that's a non-starter.

I'm happy with clones or injections provided they're the cloned from the official events. And I can offer any Gen1-6 Pokémon in return.
