Hi guys, hi have some quiestions about the Moon Cards.

1) In the CARD "Fire Aura"
When a friendly model attacks and does not have an assist bounus, etc etc...
---------
Fire Moon Effect - The model gets +3AT instead.
Is this effect hooked to the previous condition? (When attacks... not have an assist...)


2) In the CARD "Decoy"
When a friendly model activates, play this card to have the model switch places with a friendly model within six soaces. No LoS is required.
---------
Air Moon Effect - The model may switch plasces with any model within eight spaces.
Can I use this effect at any time, if it is not my turn, too?
Example:
If my opponent attacks, can I swap the models?
If so, he loses the turn of attack or can he change the target?


3) In the CARD "Adrenaline"
After a friendly model makes an attack or ranged attack roll, play this card to reroll one of its dice.
--------
Earth Moon Effect: The model rerolls all of its dice.
Is this effect hooked to the previous condition (When attack... etc) or can I use this effect to reroll the defense dice or reroll other??


4) In the CARD "Smoke Bomb"
When a friendly model activates, if no enemy model has Los to it, play this card to give in Stealth.
Can I use this action even after attacking?
Example:
I move, I attack an enemy model that dies, no one sees me, I play the card.
--------
Void Moon Effect - The model may get Stealth, even if enemy model has LoS to it.
Can I use this effect even on a non-active model?
If so, at any time, even in the opponent's turn?
Can I use this action even after attacking?
Example:
I move, I attack an enemy model, I play the card.

Thanks for the answers, in advance.
