Each board will have a fixed strategy and special event/terrain.
At the beginning of each round the TO will flip a card from the top of a deck. If the card is a heart/ram or a joker than the following rule will be in effect for the duration of the round.
Love is in the Air
Models attacking a model of the opposite sex receive a negative twist on CB duels, models attacking a model of the same sex receive a positive twist on CB duels. Constructs are sexless and neither rule applies to them.
