Reviving troops questions

[monkeydog]

1. Can inquisitors resurrect any fallen troops including level 5's and magic immunities such as black dragons?
2. Will sacrifice allow you to get more troops than you started with as long as you have enough leadership to control them?
3. If you attack during your current round, then cast time back, does it still return you to the previous round, or does it return you to the beginning of the current round sense you have actually used your turn?
