The INFINITY STONES

You have two ways to play this deck:

You can play the stones and then destroy them with Killmonger, and you have Death for other turn.

Or you can play the stones to give Thanos 20 of power (playing Black Swan to ease the play of the stones).

In both options you should play the others 1 cost cards (if you go for the first option they can help you to subtract more power for dead) they can be useful (Shanna too).
