Some results for utility land testing in the Miracles matchup:
Urza's Factory is playable. Once it gets going you're only worried about Mentor racing you or Blood Moon / Back to Basics shutting you down, so play accordingly. Only 2 post-board games of testing with this.
Similarly, once a land that requires 7 other lands to function is playable, so is Eye of Ugin. I believe the best card to get is Emrakul, the Promised End (could be wrong), which is usually castable on 8 lands (assuming Urborg is in play to make Depths + Eye tap for mana) since Eye reduces by 2 more. I tested this for 2 post-board games today. Really screws with their setup and can reset their boardstate, hand, and/or top 3 to clear a way for Marit Lage, particularly if Hexmage is already in play (can combo immediately after their extra turn). Are you going to use it like a Mindslaver and absolutly destroy them? No. However, they do need to Force / Counterspell it to stop it from being inevitable, and it is certainly very annoying.
