ty for making the game ! 
I think if we change this ,we can make the game faster and better.
I know the rules says,when u put a crystal, u can CHOOSE either the ones not used yet or the ones on the portal.
( Either by taking a crystal from their stockpile Or by moving a crystal already placed on a portal)
but, WHY would u move a crystal instead of taking a crystal from stockpile?
So my suggestion is AUTO taking a crystal from their stockpile when u can do it.
