This deck is not your typical Carnage deck. This deck about control and includes all the cards you need to control the game.
Turns 1 - 3 are used to do as many of the following as possible:
* Destroy Bucky Barnes to retrieve Winter Soldier
* Destroy Sabretooth to move it to another location for 0 cost
* Destroy Nova to give all other cards +1
You can do the above with either Carnage that gives +2 for each card destroyed, or Deathlok , or by placing them at a location that says On turn X, destroy cards at this location, fighting, anything that causes cards to be destroyed.
By this time you should have secured at least 1 location.
On turns 4-5, use Elektra and Gambit to get rid of some opponents cards to level the playing field. And use Klaw on your 2 other weaker locations to take your 2nd location (possibly 3rd) location.
Finish the game with Leader to make sure anything they play on turn 6 is duplicated on your side so they dont take back control. Leave a spot open in every location for this to have full effect.
