LF: Darkrai from Legends Arceus, FT: Mythical as insurance

I'm looking for someone with a Darkrai caught in Legends Arceus so I can get it registered in the Home dex (since I don't own BDSP). I will trade my own non-PLA Darkrai or other Legendary/Mythical as insurance (to help complete your National Home dex, for example) to then trade back to the respective owners. Thank you in advance!
