You don’t have to choose a target for Heritage Reclamation if you choose its third mode. However, if you do, and that target is illegal at the time Heritage Reclamation tries to resolve, it won’t resolve and none of its effects will happen. You won’t draw a card.
Choose one —
• Destroy target artifact.
• Destroy target enchantment.
• Exile up to one target card from a graveyard. Draw a card.
