When Baron blade is reduced to zero hit points, he flips, and has his health restored. Fanatic, if she has her Aegis of Ressurection out; upon being incapacitated is instead healed to 10hp. Besides the Aegis, are all other cards in play belonging to mentioned charcters destroyed when these two events occur?
Nope. Welcome to the forums!
If they destroyed other cards uopn activating, it'd say so in their text :).
