I'm trying to figure out how to make Emerging Colossus and Stirring Sands work. I don't have the cards to make this yet so I can't test it out. I'm fairly certain the key is to use Emerging Colossus and Invoke the Waystones. This is probably far from something viable competitively, but it's something I want to build in the future.
If you have any other ideas on how to make it work feel free to let me know.
