You could have Gardevoir use the "light screen" and "reflection" as shields (condensing them around one arm) you can also teach Kadabra/Alakazam to use his spoons as blades (as the anime shows Oshowatt using his shell as sword, it should be possible for me to use them as swords, plus the Psycho-slash move must come from somewhere)
I think that when getting modifiers, the loss of potential of the pokemon at the light aurora grade should lessen by half. Thats because if they got a modifier at the purple potential and then upgraded to aurora the pokemon would have saved half the potential they would have lost otherwise. Just saying so that the system is more balanced, beacause it doesnt make sense like that.
