Hi there, good to hear another long time no see shiny hunter.^^
The last two shinies I remember the most from you were the snivy (what a long hunt!) n shiny Deino (that one is cool since from RE).
About the suggestions, I can suggest the shinies I've got from 3rd gen or plan on hunting: Gulpin, Shuppet, Spheal, Clamperl, Sableye (unchainable n RE), Beldum, fossils, etc. From LG/FR: starters, eevee, game corner, hitmon, fishing (horsea/shellder), Lapras, safari zone, fossils, koffing, paras, hoppip, spinarak, ledian/ladyba, etc. And of course there are legendaries.
My hunts are going slow this February, I haven't got a single shiny yet. Real life makes me too excited to hunt, I hunt more during weekends. My current hunts are RE on route 3 n 13 water route in fifth gen, Palkia in JPN Pearl, Latias in US SS and Clefairy in US LG Game Corner. I hope I can get at least 1 shiny this month. The Palkia, Latias, Clefairy and route 3 JPN BLCK have gone over 10k. Thanks for asking.
Good luck for whatever you're or plan on hunting.
