Tactics for the Swamp (Fortress).

1. There's a chance that Bronze might start without Warlocks; you need to calculate it. His Warlocks are placed in the second stack, and there are hands dealt per stack – 123, 12, 13, 1. The probabilities are different for each, with 13 being the rarest, in my opinion. All the others are likely equally probable, so calculate what the probability is that he will have Warlocks, which is somewhere around 60-70%, and the rest is the probability that he won't.

2. It definitely doesn't teach.
3. I just tested it, and it teaches Eagle Eye when there's resistance, just like Imps drain mana when there's resistance.
