That's one of the cards that I never put in my deck, but I usually grab it during my Discovers.
A lot of times they get shut down instantly, so I've rarely gotten much effect out of them, but they work as a great decoy. It's too risky for the opponent to keep them alive, so they become the prime target while you get your other pieces in order.
That's why I add +2/2 bloodtap in my hand first and than deploy them with as many taunt cards as possible. Mostly the spidery thing that summons two copies of it. Also fortified by +2/2 and +1/1 on the board. Mostly brings me victory. In this game I've put out 2 of Maw/Paw and discovered third one. I was torturing the opponent with 1 health for a loooong time :)
