You're all misunderstanding how to use Mutanus. His Devouring Attack is actually his least useful ability. Devour and Scaly Taunt are actually very good.
Here's how to use him:
Bring a full murloc team- Murk Eye, Morgle and Mutanus. You'd think that you'd want to devour Murk Eye's tokens- you're correct until you upgrade Devour to rank 3. Devour rank 3 eats the lowest health murloc and gains its stats. Ideally, you'd want navigator's amulet and a highly upgraded felfin nav on your Murk Eye, so that you can keep buffing your murloc's attack. On the turn you use Devour, do not summon tokens. It's actually much better to eat one of your own buffed murlocs, either Murk Eye or Morgl to create a supersize Mutanus. This is only viable for PvP or final bounty bosses.
When you're running bounties, there's a chance to get a treasure for Mutanus which sets his health to 3/6+ but only allows him to take 1 damage at a time, regardless of critical hits etc. Buff him with Murloc Missile from Morgle to health buff and felfin nav, while spamming Scaly Taunt. He becomes an immovable object- completely unkillable in every sense of the word. Then you will want to attack the opponents with Murk Eye's 1st ability to bring Mutanus along in the attack- Bubble Wand or the immune treasure you can get would make this even better. Use Morgle to heal Murk Eye, make sure Morgl acts first for the extra buff.
Whenever you get the aforementioned treasure and comp, any bounty is a breeze. I have completed every bounty with my full murloc team. I've hit 5K PvP rating with this too.
Very strong tech against dragons and Diablo + Cairne, fire comps and Tavish with Dragon's Skull equipment.
