Fading 5 (This enchantment enters the battlefield with five fade counters on it. At the beginning of your upkeep, remove a fade counter from it. If you can’t, sacrifice it.)
Remove a fade counter from Parallax Nexus: Target opponent exiles a card from his or her hand if Parallax Nexus is on the battlefield. Activate this ability only any time you could cast a sorcery.
When Parallax Nexus leaves the battlefield, each player returns to his or her hand all cards he or she owns exiled with Parallax Nexus.
