I somehow got it in my head it was in wasteland, sorry. In tomb you would be even better off. Just keep trashing Allies and the environment will do the job eventually.
A Best-Case Scenerio
Tomb of Anubis has Mdjai, Challenge of Fire, and Swinging Blades in play. Say either Challenge of Fire or Swinging Blades were put into play on the Environment turn, doesn't really matter which. That'll be 6 damage to all the limbs, 1 to The Scholar, and 3 to Mdjai. Then, Akash'Bhuta can play whatever the heck she wants, as long as it is not Disrupt the Field or Rejuvenating Entropy are never played. Then it doesn't matter what the heroes do, as long as they do not impede the environment. Then as long as the Environment doesn't cause Akash'Bhuta to play Disrupt the Field or Rejuvenating Entropy, the three previous Environment cards will once again do 6 damage to the Limbs. Destroying the 3 Mountainous Carapaces first, totally 27 damage to Akash'Bhuta. Then the rest of the limbs, making the final damage done 120. With her HP previously being 96, she would be defeated.
