Having a fair amount of success locally, going 2-1 most of the time. Just changed up the sideboard to account the the weakest matchups (Tron, Scapeshift).
Monastery Mentor has been incredible as a threat since it seems manageable up until you cast 2-3 spells, and by then it is a little late for the opponent to do much of anything to stop the momentum.
Ajani on the top end has proved invaluable in a bunch of matchups, especially in greedy decks like Jund and Abzan. Ultimately, though, Ajani will phase into the maybe board once I have a more impactful replacement.
The Infect matchup is insane, and the Dredge matchup is not as bad as it seems with main-decked Anger of the Gods and Kalitas along with hate out of the board. Burn is 50/50 with Collective Brutality, Kalitas, Blessed Alliance and Shambling Vents in the main and a third Blessed Alliance, Second Kalitas, and second Collective Brutality coming out of the side.
This deck does struggle from running low in the late game, thus the concession to Painful Truths (potentially needs 1 more).
UPDATE (1/30/17):
Added 3 Liliana of the Veil and took out the Mentors. They are just so squishy, and ultimately Liliana is a much better top-deck in most matchups. Added Pithing Needles to the rotation since this deck is so, SO bad against Tron/Scapeshift, and it can turn off troublesome permanents like Creeping Tar Pit. I want to experiment with Guttural Response (seems really spicy against Grixis Control and Jeskai Flash, both of which are prevalent locally).
I haven't played with this configuration yet, but I am very excited. Seems a lot more powerful.
Also, tested with Chandra, Torch of Defiance this past weekend. It felt powerful, and being able to exile a discard spell off the top with her +1 seems relevant a certain percentage of the time in combo matchups, but ultimately she is expensive and clunky at RRXX, where I am already trying to get BBX by T3. Might end up with 1-2 Graven Cairns in the main over 1 Godless Shrine and 1 Dragonskull Summit to make that more doable.
