Revive shortage coming ...
We successfully 6-manned a Kyogre with Hydro Pump, but he knocked out two full teams for each of us. Given that I had to revive 12 mons, and I only get an average of maybe 4 revives from each raid, I see a great revive shortage in my future.
At the moment I have 1 revive and 83 max revives. But that will be used up rather quickly by a week of Kyogre raids.

If you are raiding with pokemon you intend to power up anyway AND you have the dust to power them up, you can use dust to revive your pokemon. They battle, faint, then power it up (maybe twice or even 3 times - Gengar > 30) to get the 1-3 HP then potion. This mini revive helped me save 20 revives taking raikou from L20 to L30 ... and many others, too. Gotta have the dust though. Also, obviously doesn't work if you are using L40 pokemon.
