What do you do?

I got 42 dead pokemons, my shit gets kicked in every single Kyogre raid, as it loves to spam its strongest moves, you can't really buy revives without selling a kidney.. i know you can lvl up once and heal but that also depletes all my healing options in no time.

What on earth do you do in this situation? Cuz pokestops/gyms are simply not giving me any revive stones..
