Attacking with Unstoppable Slasher, enemy casts Rid'es end to target tapped creature and exile it. I cast Go for the Throat on my own slasher so it gets destroyed instead of exiled and can return to the battlefield. However, it does not return, even with counters for another target spell or anything. Just dissappears. Nothing on board would force dying creatures to be exiled instead, and it was attacking, so no it did not have counters on it, nor was it available for the target spell as it was sent to the graveyard and should have been 1. Temporary untargetable, and 2. It was dead before the exile could resolve in any case. This was in ranked and happened a few turns before this board state screencap.
