With most of the good taunts rotating out, this might see some play. But unless you have Mech synergy Rotten Applebaum will be better.
Hmmm... no. This is better than the applebaum. This heals you for more, 5 or more), is much better when you are at full health, and protects your other minions better. Yes, it is 1 mana more expensive, but that is because it does much more.
This thing is a nice taunt. Overall, it protects you from 10 damage and it can work with some deathrattle synergies. It is super annoying but it does its job and I think it will be used since some of the stronger taunts are rotating out.
