It may just be me having terrible shiny luck but after returning the dragonite skull in Pokémon black can you still shiny hunt or is it just bad luck that I can’t seem to find a shiny sewaddle
It’s just bad luck. Your odds are 1/8192, but sometimes the game will just hate you and won’t give you a shiny for much, much longer. I recently had a hunt go for over 17,000 encounters before I found anything.
