Currently I have two targets I want to get done, hopefully before next month. The first being Seedot who is well overdue, secondly Turtwig which I am not even set for hunting yet. Both are going to be attempted through MM on White. As for SoulSilver it is currently only used for earning coins from Voltorb Flip. Also I am guessing if I run into a shiny on Emerald it will be through Battle Factory which has happened a few times in the past.
Current hunts
Seedot MM- 2220 Eggs
Future hunts
Eevee through Game Corner(Starting Dec. 31st)
Turtwig through MM(If Seedot permits)
