Change Pokemon type to ???!
I actually figured out how to change a Pokemon type to ??? Type.
1. Get a PURE flying type (will not work if it has 2 types. MUST be just flying type)
2. Make it's ability compoundeyes
3. Use roost
It will change into a ??? Type to make it easier use the Pokemon modifier, ability modifier, and move modifier action replay codes.
Have fun being an unknown type! ;P
