1. No-one goes in at that moment. The next one to attack Tokyo goes in on their turn.2. No, "discard" card must be used immediately.
3. Nothing happens until you end rolling the dice and then resolve the effects. If you have one claw, you resolve an attack and if there is no-one in Tokyo, you go there.
4. You can only yield when you are attacked in Tokyo. (Claws are resolved. Note: there are other ways to cause damage that are not attacks.)
