Personal titan - number of moves

I have already saw an idea for personal titan. I would say it could be done also in a different way.

  1. You get a personal titan
  2. You have 6 attacks (you can not use same heros, just like in wars)
  3. You have limited number of moves on the board you can do, lets say 20 (no time limits)
  4. From the personal titan chest when and if you get 3* or 4* AM you get 2 kinds offered so you can chose what you like.

To add a twist triggering diamond doesnt count as a move.
I think this would make great use of element link.

Any opinions
