If they bring Megas to Pocket, what style of evolutionary line would you prefer?

>Old
Charizard EX(Basic) > M Charizard EX(Stage 1)
Latios EX(Basic) > Latios EX(Stage 1)
Lucario EX(Basic) > M Lucario EX(Stage 1)

>Modern
Charmander(Basic) > Charmeleon(Stage 1) > Mega Charizard ex(Stage 2)
Mega Latias ex(Basic)
Riolu(Basic) > Mega Lucario ex(Stage 1)
ex is not EX but they can work in a similar way.
