Doubles battles seem to be buggy with revives.
I'm not sure if the amount of Pokemon in the party matters, but we tried it with Four.
When the last Pokemon alive is sent out alone, if it dies in the same turn as you revive another Pokemon, the revived Pokemon gets sent out but the UI with its HP and stats doesn't show up, meaning you can't target the pokemon with single-target moves. The battle won't end since you have Pokemon alive, but your opponent can't do anything but switch or use items. You can still attack normally, or switch, or use items. Multi-hit moves were not tested.
If you have one Pokemon alive and sent out without the stats showing, reviving another Pokemon brings out the second revived Pokemon's stats window. However, when attacked, it hit the first pokemon (who can't be targeted) instead.
Also, right at the end of the video, you can see for whatever reason, it attempts to send out a Pokemon, triggers Intimidate, then wants to send out a new Pokemon, causing an endless loop.
It's kind of tricky to explain for me so I've decided to attach the video link of the battle.
