What should I prioritize?

which shiny hunts should I try first? I want to get most if not all of these before the 6 months is up. which are the best to do together/first and which should I leave for last

shiny type null (hunt has started)

shiny Wishmaker jirachi (set up is done and hunt has started)

shiny ranger manaphy (not set up yet but I have an unfinished ranger)

shiny japanese emerald mew (should be getting an emerald tomorrow)

shiny partner cap pikachu (hunt has started)

shiny spinda (not started)

shiny celebi (not started or set up but I have VC unfinished crystal)

finishing purifying my shadow pokemon

catch the rest of the shadow pokemon in XD and colosseum

All of them have to be home compatible and generally legit but I would not mind using DNS exploits or some glitches/homebrew to get some of these
