I meant that you don't need a specific ID/SID to hit any spread in BW2. I'll see if I still have the excel, but you should just do shiny charm ID/SID abuse for HG/SS and get better spreads.
If you could message me that excel sheet that would be great. In the meantime I am still looking for ID/SID Shiny RNG Spreads for HGSS, if anyone else here has the workable spreadsheet I would be grateful.
