It’s fine, I cast revivify
DM: I cast counterspell
Oh, hey satan
Is it possible to counterspell a counterspell?
You can counterspell as a reaction, so yes, but you’d be using 2 different spell slots and a reaction to cast one spell, so it’s still not great.

Worth it to revivify. Also it likely wouldn’t be on the same caster as counterspell and revivify don’t overlap on spell lists as far as I can think.
To make this extra stressful, Revivify is the only resurrection spell I allow if I’m running 5e. :)
(Okay, to be fair, that doesn’t mean I ban player resurrection in heroic campaigns. I just want it to be more of an ordeal, y’know? So it has to be a quest, or require bargaining with some kind of supernatural entity, or come with a price or chance of failure, etc. I just don’t want it to be “I cast the spell, or go to someone who can cast the spell and pay some gold.”)
poor molly :(
