Good luck man. Don't be discouraged though man. 25 boxes is only 750 eggs. Trainer10713 was up to 2100 eggs, and I hit 1570 for one of mine, which for me was 50 full boxes.About a week ago I started breeding for a shiny Abra. I banked almost all my mons, and I filled up 25 boxes with eggs. This morning I hatched my last egg, and with no luck.. I have the Shiny Charm and I use the Masuda Method. I'm not really familiar with TSV.
Only a few times have I ever managed purposely hatching a shiny using this method.
Magikarp at 93 eggs
Chinchou at 341 eggs
Kabuto at 277 eggs
Guess I'm going to continue with the Abra. Wish me luck *__*
