If you have 2 Energy Barriers in play, can you use both interrupts on a single attack? (I am thinking yes, because it's the same timing window and two different instances of card ability)
If yes to the above, how would you resolve the following: Villain at 1 hp and there's another villain stage left. Villain attacks, does 2 or more damage, Player triggers both energy barriers.
Does only the first instance of damage trigger, bring the villain to 0 HP and reveal the next stage, end of interaction
or
Does the first damage bring the villain to 0 HP, reveal the next stage, deal the 2nd damage to the next stage. And when would the villains new stage's "When Revealed" triggers fire? Between the first and second damage application? After the 2nd damage?
