I removed Leyline of Sanctity from the Sideboard for a couple reasons. The primary reason was that Leyline of Sanctity really performs best as a 4-of but I did not want to devote that many of my Sideboard slots to just a few match-ups. Instead I added another Rest in Peace and another Pay No Heed. Both cards are great against a wider variety of match-ups than Leyline. Pay No Heed doesn't see much play in Modern (if any), however, its great, cheap tech against Burn, Bogles, Infect, and Scapeshift. Please note that Pay No Heed DOES prevent damage from multiple triggers of a single source in a same turn (ie Valakut, the Molten Pinnacle damage). The additional Rest in Peace will allow me to draw it sooner in the game against any strategy relying on the graveyard (Living End, Dredge, or Reanimator).
Finally, I replaced Make a Stand for Eerie Interlude. Both cards are used against the same match-ups (mainly Control), however, Eerie Interlude seems to have more upside as it takes advantage of all the deck's Enter-the-Battlefield triggers. Saving my battlefield from a board wipe and gaining life at the same time seems very advantageous.
I have included the deck's archetype breakdown below. Please note it remains the same as it did in the last update because I have not had much meaningful gameplay play lately. Hopefully that will be changing in the near future.
PS: I plan on taking this deck to GP Hartford in April 2018.
