Can I get infinite Mews if:
-I get the Mew on My Pokemon Ranch
-Withdraw ALL the Pokemon I deposited(Including Mew after trade)
-Delete save data on Wii settings
-Deposit my Pokemon as much as I can at a time(Based on ranch level)
Yes, you can!
You'll have to upgrade your ranch to fit it all again of course, but it is entirely possible. You could just change the time on your calender though.
