On deadpool daily 1-star battle, I have a level 50 storm and a level 1 Spider-man. Both died in my first attempt, so I Revived storm. No reason to use a valuable revive on a level 1.
I was unable to play the level without also reviving Spider-man. I wasn’t able to deselected Spider-man from my team, since they are the only two 1-star characters of have.
There are workarounds (wait five minutes, spend another revive), but it seems like a bug to me.
