This is nice. I will go ahead and use it as a reference to aid me in teaching new people.
One comment: I think I would add that Werewolves gain additional benefits from becoming the strongest minion on a base (their "alpha wolf" flavor is showed in 3 cards of their faction, so it could be mentioned somewhere.) Other than that, this is pretty spot on.
Note that the actions that allow bonuses do not say that they must be played on one of your own minions. It's probably better to put them on an opponent's King Rex, a treasured Dwarf, or Cyberback than on one of your own werewolves. It's less likely to be countered that way. As the action is still yours, the effect remains yours regardless of who owns the minion.
