It's great to see that you have a deep understanding of the Gods Unchained mechanics and meta, as you've identified the challenges faced by the "big beast" archetype and developed a creative solution.
I must admit that it's a clever strategy that you choose to focus on the strong removal options to reach the 5-6-7 mana range. And that you intend to utilize like Shapeshifter, Sudden Bloom, and Ember Oni, to maintain board presence and control.
Thanks for sharing
