This card is way better than Thaurissan IMO. Sure Thaurissan is the more threatening card overall, but it comes out on turn 6 basically limiting it to combo/control decks, and only gives you tempo boosts turn 7 on. This thing can accelerate your tempo plays starting turn 3 putting you so far ahead of your opponent it's not even funny. Imagine plopping down this and following it up with a Tol'vir Stoneshaper. Sure you've lost some tempo playing a 2 mana 1/1, but your turn 3 play is so much more powerful than their turn 3 play that it can reasonably trade against both the opponent's 2 drop and 3 drop and still live, then add a turn 4 Earth Elemental and you're just hitting paydirt.
