The stat breakdown of this card puts it above Sludge Belcher. When evaluating divine shield minions the minion's health is counted as 1 until the shield is broken so this card is worth a 6/5. It is not better than belcher overall for a few reasons. One, it has an aggressive stat configuration and taunt minions are for defense. It's weaker against aoe and destroy effects as well. It will trade better than belcher in most cases though. It is a good card and should see lots of play in standard. And it costs 5 mana which means it has little competition.
