Nécromancie (Necromancy)
Nécromancie 

Quand la Nécromancie arrive sur le champ de bataille, si elle est sur le champ de bataille, elle devient une aura avec « Enchanter : créature mise sur le champ de bataille avec la Nécromancie ». Mettez sur le champ de bataille, sous votre contrôle, une carte de créature ciblée depuis un cimetière et attachez-lui la Nécromancie. Quand la Nécromancie quitte le champ de bataille, le contrôleur de cette créature la sacrifie.
