Keep me informed on your findings? :D
Also, I realized something.
The battle tower or frontier is confirmed. Basically
If Sky pillar was hidden, yet we find out Rayquaza has a secret to Mega Evolution
Sky pillar CONFIRMED.
Meaning it likely remains as q post game thing.
Now it seem very likely that either A:Battle tower Returns
Or B:Frontier Returns
I hope it's B. I need move tutors lol.
