Another card that has been great for me in Windgrace is Jokulhaups, since it is basically an Obliterate without the uncounterability. However, you run Boseiju, Who Shelters All for uncounterability.
EDIT: Didn't read the thread well enough, you cut them already, lol.

EDIT2: Tireless Tracker is a card that is great with Windgrace, too.
A good win condition for Windgrace is also the Dark Depths and Thespian's Stage combo.
Valakut, the Molten Pinnacle and Prismatic Omen can do work, too when combined with Scapeshift or Splendid Reclamation.
