Here's an interesting question that occured to me yesterday:
Rules Reference page 8, card abilities: "A card ability cannot be resolved more than once during the timing specified on the card."
New Chewy: "After another friendly ship at Range 1-3 is destroyed (but has not fled the battlefield), you may perform an attack."
In the instance where a single attack would destroy 2 ships (ruthlessness, assault missile, a huge ship squishing two ships, etc), would Chewy's ability trigger twice or would the fact that both ships are destroyed at the same time limit Chewy to only attacking once?
