Thanks for the merge 4RM3D, I had forgotten about that previous thread.
In the last thread, I proposed to remove the summoning of opponent's units. This seems to be the easiest solution.
In the older thread, we were discussing to have the opponent draw a card in hand (like in beta), so that it can be played later. This seems the most interesting mechanic to me, but there are issues due to hand limit and an opponent who has passed not being able to play anymore. This could be solved by removing hand limit and a "Truce" whereby a player who has passed is "unpassed" and is then allowed to play or pass again.
