Why settle for two or three wolves when you can have seven or more of them instead?

If just having a ton of 3/3 wolves isn't enough for you - why not have them fall upon your opponent's creatures like, er, a pack of wolves?

With Howlpack Alpha, you get a free creature token every turn for zero mana.
It's crying out for a Juniper Order Ranger.
That guy's going to get large.
So now you're getting a lot of creatures with counters on them.
Maybe they're still too small…
And maybe you still don't have enough of them… EDIT: Just a note on how insane Doubling Season is… Howlpack Alpha + Doubling Season =
two effectively 3/3 wolves
every turn add J.O. ranger =
two effectively 5/5 wolves
every turn, ranger grows +2/+2 each turn add Plaguemaw Beast = Sac.
a wolf to grow all other wolves and ranger +2/+2

Here are some ways of generating more wolf tokens to play a swarming strategy.
This kicker might be more appropriate to EDH/Commander games where mana is more plentiful, likewise Master of the Hunt is expensive but if mana is plentiful, it might be an option.
For true EDH play, here's your general for this deck:

These cards have Human and Wolf or Warewolf in their creature types, and would gain +1/+1 from the Mayor regardless of which face was up.
These (formerly human wolf)
cards are (now, Sept 2011) werewolves and benefit when Howlpack Alpha is face up.

Metal wolf!
Not only does he get the boost from the Mayor/Alpha, he also boosts the Mayor/Alpha if you set his type to Werewolf.
It's a win/win partnership!
(I've noticed that Pat has requested that we amalgamate our answers into one decisive one, so my final answer is this guy plus the two other cards I've posted so far.
A pretty good start to creating a nasty pumped-up werewolf package.)

In the Innistrad set, at least 1 of the double faced cards is a werewolf with the ability to upgrade other werewolves and wolves in play.  What other wolves have good potential to combine with the Mayor of Avabruck//Howlpack Alpha card?  I'm thinking primarily of Commander games, but if you think something fits a different format, please note that.

A Juniper Order Ranger, as well as the cards Human and Wolf. These cards have Human and Wolf or Warewolf in their creature types, and would gain +1/+1 from the Mayor regardless of which face was up.   It's also crying out for a Juniper Order Ranger.
