Thanks! I almost bailed on it and played something else at the last minute, but I figured it'd be fun at the least. The DE/Hekarti matchup was one of a couple that had me worried, and is a large part the reason for the three Pilgrimage in the deck. It certainly doesn't "solve" the problem of the quest, but does at least give you an out that lets you pull off the combo if everything else is running smoothly. In the fairly limited testing we did, the matchup proved to be pretty chaotic.
There are a lot of different ways you can go with the basic Glory/Thrower combo, so it's very possible there's another version that's better. I had many, many lists!
Re: Clamatius: Mill does certainly struggle against rush, but I think it is in the 50/50 range against a lot of good decks. It's just very draw-dependent since there aren't all that many mill cards. Often the distribution of Plague Monks and/or Frenzied Witches will more or less determine the game against a mid-tempo deck. The decks that tend to have the best unit removal (Chaos and DE) are also kind of vulnerable to milling naturally.
