Let’s analyze it.

What types would Gun and Vent be?

Well Gun would be a fire steel type. And Vent would probably be ground steel.

Assuming Gun’s attack is type fire, it would be very effective against the steel typing of Vent, HOWEVER fire is not very effective against ground.

It would be normal effective since the ground type cancells the effectiveness out. Therefore if anything, Vent would only take a bit damage and not lead to an instant death of Y/N.

Aside from that, we all Pokémon cannot legally attack trainers unless it’s in Hissui. Which I doubt we are in during ISWM
