Therefore, its possible for either a Basic, Stage 1 or Stage 2 to Mega Evolve, as the card itself will specifically state what you can place the Mega Pokmon Evolution card onto (for example, Put M Pidgeot-EX on the Basic Pokmon-EX ) The plan for this is to simply do normal Mega Evolutions, like how they were in the video games
The only thing missing perhaps is the ability to target planeswalkers (and battles)
