A free mode for 1 player would be nice where you can put any unit, augment, weapons, etc., both on your side of the board and on the opponent's side, and be able to simulate combats. It would be useful because it would allow you to test things more easily, see how an augment interacts with a unit, how a unit works, how certain synergies interact, which augment gives the most damage to x unit, etc., being able to manipulate rules such as being directly on turn 5... It also makes the process of building a deck more enjoyable, since you can try things while you create it, in addition to being easier and faster to optimize it. It also allows you to simulate battles against other decks to see how to play against them. Finally, you can end up taking advantage of the mode to create puzzles or situations to solve like in chess.

This will be a great feature! Pretty sure this is planned for post open beta, a practise tool where you can try stuff.
