Alastor clarification

I think it's more useful to give your prey a Polaris Coach.

Vehicle. Haven. During your untap phase, move 1 blood from this vampire to the Polaris Coach or burn the Polaris Coach. While this vampire is acting, he or she may burn one counter from the Polaris Coach to get +1 stealth for the current action. During undirected actions and actions that are not directed at this vampire, he or she cannot block or play reaction cards. A minion may have only one haven and only one vehicle.

mm, he can still let the polaris coach burn during his untap so...
Maybe you'll have a simpler time playing Blind spot or banishment ?

Shackles of Enkidu?

Play it on a vamp low on blood, ie 2 or less, fame him, and then give him the talbot's chainsaw.

Sure... and it's neighbor pays the cost and the weenie rush you...

Yea but that's part of your plan : you chose to play a Cold Aura+ Machine blitz deck.
