Usually I'd never publish teams with a Blizzcon pet but for those people who have the recommended pets and want to shorten pet battles to the extreme just to enjoy their nice pet collection, have fun!
Righteous Inspiration combined with Greench's Gift is already a devastating combo vs, Beasts but still not enough for Jammer so I tried to find stuff to buff it even more and Rabid Strike with another 50% damage increase looked promising and Corpse Explosion helps to get rid of that Squirrel without wasting turns on usual pet swaps.
The strategy offers a TD script that can be used with the TD Script addon. You can copy the script by clicking on the button to the left of the pets.
At least one pet in the strategy cannot be obtained anymore. If you have it, congrats!
