A retrace card cast from your graveyard follows the normal timing rules for its card type.
2008-08-01
When a retrace card you cast from your graveyard resolves, fails to resolve, or is countered, it's put back into your graveyard. You may use the retrace ability to cast it again.
2008-08-01
If you cast Worm Harvest from your graveyard by using retrace, the land you discard as an additional cost will be counted by Worm Harvest when it resolves.
2008-08-01
If the active player casts a spell that has retrace, that player may cast that card again after it resolves, before another player can remove the card from the graveyard. The active player has priority after the spell resolves, so they can immediately cast a new spell. Since casting a card with retrace from the graveyard moves that card onto the stack, no one else would have the chance to affect it while it's still in the graveyard.
