Say a player dies to {Blood reckoning} or really any card after they declare an attacker and I have no blockers
Question is. If they lose in response to the attack or I were to play an instant such as {sign in blood} {Toil // trouble} or what have you.
Do I still take attack damage? Or does their stuff get removed immediately before I would get hurt?
These were sorceries not instants but whatever
They lose the next time they would recieve priority, as losing is a state-based action, so yes, they would die before damage is dealt.

Yay. Stupid hydras -.-
