Slaanesh and Tzeentch Settle it Soviet Style Take Two

In one of the Realms of Chaos, Slaanesh  (in one of her non-GW forms) 

                             and Tzeentch are arguing about who is the cooler Chaos deity.

                           
                              They agree to settle it with Soviet cold war era kit.

                              And 5th edition Warhammer Magic Cards.

                              Tzeentch soon has had enough.
