Abilities » Hero's Spirit
Palafin ex's "Hero's Spirit" Ability is very literal. You can put it into play only with the effect of Palafin's "Zero to Hero" Ability; you can't put it into play any other way. The only exception would be if something like Hex Maniac or Garbotoxin are used, which remove Abilities of Pokemon that are in the hand.
