Let's open the ability table
Poison Heal looks like the best out of the list, but it may be too good. Magic Guard is #2 place, but we don't want semi-STAB BoltBeams coming out of 344 SpA. ESPECIALLY when combined with STAB Surf to 2-hit Swampert and Tyranitar, 339 speed, 94% of 4/0 Latias's Special Bulk on both sides, and entry hazard immunity do not help at all.
