What will happen if i destroy Omoni xp2 from his own ability and i target him (as dead) in discard pile? Will he return in play in my home?
Battle/Open: Destroy one of your Goblin Personalities: Bring a target Goblin Personality from your discard pile into play at Omoni’s location, ignoring its Gold Cost.

This is not legal. When an action is taken, required targets are chosen before costs are paid (see Abilities and actions). You must target a Goblin Personality in your discard pile before you destroy one of your Goblin Personalities, thus Omoni itself is never a legal target for its own action.
