I figured out a way to get the absolute maximum AFAIK, if anyone can EVER calculate this.
One deck needs to get as many mind gates as they can in the first turns. Preferably losing the coin toss, and getting 6 mind gates, 2 aether pillars, and drawing aether pillars every time after that. They would have to copy all they can, obviously.
The deck would include enough aether pillars to utilize a crapton of mind gates.
The other deck would need to draw the mind gates soon after the opponent can start utilizing them so that the 6 mind gates can copy from one on the top of the deck, which gives the opponent 42 total mindgates. (this is getting tricky...) Then the copier would have to copy bunches of stone pillars and amass as much stone quanta as they can, then get the stone skins in the last 18 or so cards. The SoDs would be drawn after that.
This deck needs to have a crapton of stone pillars, 6 stone skins, 6 mind gates, 6 SoD, and be able to rewind with a Photon and Eternity. (the first deck can copy it)
