I actually made a similar list but using the emry tamiyo bauble mox amber package as well as the alchemy card that conjures mox opal into hand. Also using kappa as a win con.
It's interesting, yeah I was also thinking a few days ago some way to exploit 4 Mox Amber now that we have so many good legends, but still haven't found a really good list, we'll keep working on it!
