Both cards trigger at the same window, as per the chose order of resolution rule, I can choose which one I want to resolve first. Here comes several questions about both card interaction.
1. If I choose to resolve Reserve Hangar Bay first, is the squadron still considered destroyed in order to resolve Grievous?
1.1 If yes, where I measure from in order to resolve Grievous? Where the squadron was destroyed or where I placed with Reserve Hangar Bay effect.
2. Can I choose to resolve Grievous first to gain its benefit and then Reserve Hangar Bay even if Reserve Hangar Bay resolution means the squadron wasn't destroyed?
