It took me a while to discover the Golem Minion -- Once you play a Myth character, though, you start to realize what a wonderful thing this zero pip cost minion is (or not . . . I'm sure its easy to miss the beauty of this ugly little guy). That in itself is super unique: Myth gets THE ONLY zero pip minion, and you know, sometimes it is the seemingly weak spells that can by the most useful.
Once you cast that you get a Living Puppet minion that helps you out in battle for the mana cost of absolutely free.
On his own, as long as you have agro, you're pretty much assured he will continue to chuck out little one pip spells and live on, nipping away at someone's life (and understandably, if you're setting up a series of traps, he may not be the best candidate for your deck), but my favorite use of him was with Angus's Sacrifice Minion spell. In fact, the golem minion + sacrifice minion + tempest got Angus through a good chunk of Krokotopia and Marleybone if I remember right.
So, trust me LOL, he's awesome.
