Yeah, that makes sense given the card choices Noctalor. I'm not sure about your statement that miracles is overrated and lacks a decent finisher. Both Monastery Mentor and Entreat the Angels are serious finishers that don't require much deck space, and Jace wins games in itself. The deck also did extremely well at GP Seattle with 8 copies in the Top 64. We don't know the conversion rate, but I imagine the deck had a good conversion rate as it doesn't have that many pilots. Anyway, perhaps that's a discussion for another thread haha.
In any case, I'd highly recommend trying the mono blue whir + chalice list. Getting to play chalice gives you a lot of game against a number of decks in the format, and in contrast to other chalice decks you have the consistency of tutors (in Whir, Transmute, Tezzeret and Trinket Mage) and pseudo-cantrips in Thirst for Knowledge. You also have strong alternate game-plans in game 1, in Jace combined with Ensnaring Bridge and Tezzeret ultimate. Plus, as a blue deck, you still get to play Force of Will.
Regarding your comment that tezz wasn't great, it's worth noting that he plays a very specific role within the deck by acting as a fifth tutor for either combo piece that can get both pieces of the combo over two turns, with the added upside of providing a way to win games that you wouldn't otherwise be able to. I was initially on four Whir, but the triple blue cost can be prohibitive.
Whir is the card that really makes the deck tick, and its cost is why I would caution against including another colour unless you have very specific reasons to. As it is, I haven't found those reasons to be compelling enough. What makes you want to play white?
@Noctalor, feel free to ask any questions you might have about the chalice build if that is the list you were talking about. I'd love to hear how you get on with it.
I played the deck I posted on page 39 (
#775) to a 10th place finish at a reasonably-sized local tournament yesterday. I played a Lodestone Golem in place of the Llawan in the sideboard, although I think the change was fairly immaterial. I'm still trying to figure out the optimal board.
I beat Death and Taxes, Lands, Grixis Vial-Smasher (basically UR Delver with Vial-Smasher) and Moon Stompy, losing an earlier round to Turbo Depths (which is usually a good matchup) and my win-and-in to Czech Pile.
