Edit: Yeah, Thousand-Year Storm is also unsafe, because it can copy Arcbond. We're relying on Sea Gate Stormcaller to get copies of Artificial Evolution and Mobilize. (and Prosperity from the layer sequence)
Edit: Okay, if taking out Dual Nature works, the next step is to fill out the ending layers. How can we generate a lot of red mana?
Edit: Hmm, without Fractured Identity, we can't give the opponent Treasure tokens or Gold tokens, so we can use those in the layer sequence. So, how about:
That would be 1 hyperstage + 1 stage + 5 layers, it looks like. I'm not sure that the changes don't require extra cards, so that's something we should look out for.
