Yes, wild dogs are playable...?
My number 3 file. The fluffy puppies are cute. With damage coming in at start phase, they can cause some damage before most things can move. Since Bringer no longer one-shots Shadow Hound, he is better at surviving.
Honestly, Fierce kinda distracts me from my generic puppies. I find myself focusing too much on keeping Fierce alive and leveling him up. If you treat him as mainly a puppy focus card though, he can probably be quite good.
