How are XY Mega references incompatible with new Megas???
Not looking for a ruling because it's been answered. I just find it dumb because cards like Mega Signal and Mega Catcher have the exact same reference but Mega Signal has an additional restriction.
I know they can't say "Mega" Pokemon to refer to all new Megas because that would also hit Mega Lopunny & Jigglypuff. They can't exclude M Pokemon because that's no longer a rulebox type in rotation and wouldn't make sense to reference.
Due to formatting, XY Mega Evolution references should be forwards compatible.
