Details:
> Haunt is a new mechanic and one of the negative tokens. When a unit with haunt is played, you select an enemy who will recive 2 damage at the end of your turn. The haunting will end if the picked enemy dies. One enemy cannot be targeted by multiple haunts. Is like a hazard but it applies only for one unit, not for an entire row.
> Banish is a negative tokens. It's utility is simple. Units affected by Banish do not go to the graveyard and cannot be resurected later.
> Poison works like Haunt, deals damage every turn, at the end of the enemy turn. Haunts damages at the end of your turns.
> A unit can be under a negative token and under a hazard at the same time, but it cannot have more than 1 negative tokens at a time.
