Rulings

From the Super Slam release notes

Battered, Beaten, and Broken’s first ability triggers when it resolves on the stack and becomes an attacking card against a hero. You will intimidate that hero when the triggered effect resolves.
Battered, Beaten, and Broken’s second ability generates a conditional continuous effect that is always checking. If you control less than 3 auras when you attack with this, then you control 3 or more auras, this will get +3{p and gain the “when this hits a hero” triggered ability.
Battered, Beaten, and Broken’s second ability is not functional while defending, or on the stack.
If you gain control of a third aura during the damage step and it causes the if-conditional effect to become active, it will get the +3 from controlling three auras but the damage will not be recalculated.
The triggered ability gained from Battered, Beaten, and Broken’s second ability triggers when it hits a hero. You will choose which intimidated card they own to destroy when the triggered effect resolves. If the intimidated card is face-down, it is made public before it is moved to the graveyard.
If the number of auras you control becomes 2 or less while the triggered effect is waiting to resolve on the stack, you will still resolve the triggered effect and it is not removed from the stack.
If there are multiple face-down intimidated cards when making your choice, you will not be able to see the cards before making your choice. The player who owns the intimidated cards is responsible for ensuring that the cards are distinguishable by the order in which they were intimidated.
Destroying the intimidated card will not trigger any “when this is destroyed,…” effects unless it is specified by the ability’s triggering condition.
Destroying the intimidated card will not satisfy any condition nor trigger any effects that look at whether an object they control was destroyed (e.g. Merciful Retribution, Ratchet Up) as players do not control the cards in their banished zone.
