I'm thinking the cagebreakers might still be out of place, as I could just as easily throw in another Mayor that's a fraction of the casting cost, giving more bonuses to the other werewolves and producing wolf tokens much earlier in the game. To that end, the parallel lives really would be just for speeding things to press my advantage (to be honest I wanted to use the parallel lives because I have one or two extras from some trades I made earlier to build my squirrel deck - which on a funny note, might take a few turns to get rolling, but it can produce thousands of squirrels in less than 10 turns... I actually set a personal record doing over 56 million damage to a friend in a casual game with those).
I actually had a question to clarify about the Immerwolf, given that you've played with/against it. Am I correct that once one is in play the werewolves do not transform back to human form unless the Immerwolf is killed? If so, man that's one mean card.
Also, if your friend is just playing casually, the Master of the Wild Hunt would be a good final blow card, as it lets you just deal damage to an opponent without even having to worry about blockers.
I guess I have some cards to obtain to see how this thing goes... thanks for all the input!
