Birddog

Everyone knows that Dogs are Man's best friend...

But Sam really likes Cosmo. So here's a voltron deck for our good puppy. With both avenger and guardian upgrades available, with no consequential damage, this dog should become a powerhouse, and Falcon should benefit from milling the weaker or nastier cards out of the way.

Falcon's a tricky hero to play, but with a trusty space-dog at his side, he might be able to terrier-ize the opposition.
