Just skimmed the rules. It looks like the custom deck construction has more flexibility. Some of the event cards have different times in the turn sequence you play them. Also the placement of gates(walls) is different. You either place them in your back three rows, or adjacent to your summoner. So you can't place them on your front row without moving your summoner, and if you are really aggressive you can place them on your opponent's side of the board. I think a lot of the other stuff is changes in layout, and stuff like that, but it has been a while since I checked the rules or played. The idea of placing a gate on the other side of the board is intriguing.
