Does a player-controlled Mastermind count as a player for card effects such as Ambush, Escape or Villains Ally cards?

Question

Accepted Answer

The Mastermind player still counts as a player for cards that name players, with exceptions. A poster quoting the Secret Wars Vol 1 rules says Master Strikes, Ambush and Escape effects don't affect the Mastermind player; one reply says Fight and Scheme Twist effects do.
