I don’t know about tier 2, but it has been pretty solid from my testing. Basic setup is 1 skyscraper, 3 capt. golds, 3 wildhearts, 3 neos alius/heat, 1 ocean, and 9 backrow of your choice. I feel like this deck with restart gets skyscraper out a lot more reliably than where the heroes dwell.
Losing skyscraper isn’t the end of the world (unless your field is filled with captain golds), and using cyclone on it means my backrow is still intact, so I’m okay with that. A second skyscraper would often be a dead draw anyway.
