Garruk is not on Innistrad (or at least we're not sure?) so Avacyn may not be affecting him.
Is it me or Is Jace becoming the "Captain Kirk" of MtG?
Liliana? Turned him into a man
Tamiyo? Paired, possibly more?
Chandra? Paired
Nissa? Paired
Kiora? Paired (loosely)
Vraska? Defeated in combat (can't woo them all after all)
Who's left?
Elspeth? she's
dead (for now?)
Nahiri? We'll see
Narset? not yet, but only time will tell.
