After Crown replays Horn of Plenty that already trashed itself, does it still gain a card and try to trash itself again?

Question

Accepted Answer

It still resolves and lets you gain a card costing up to $7, since it no longer counts itself. It cannot trash itself again because it is no longer in play and a card already in the trash does not move.
