So, the Rastakhan's Rumble self-attacking Druid needs a win condition, preferably one that synergizes with Savage Roar and/or Twig of the World Tree (since those are cards that give the hero Attack anyway). I decided to go with a Token Druid package, with Savage Roar as the Win-Con.
I couldn't see Savagery making the cut as long as Lesser Jasper Spellstone is around, even in this sort of deck.
There's not as much Twig synergy as I would have liked; this deck can use 10 extra mana, I suppose, but not in the way a Malygos Druid could. But I threw in Mojomaster Zihi as a way to take more advantage of the Twig. (Play him just before popping the last durability of the Twig; now you have 10 mana and your opponent only has 5.)
