I have been using Necromancy for awhile, but I recently noticed the errata that states:
Quote:
You may play Necromancy any time you could play an instant. If it was played any time a sorcery couldn't have been played, it gains substance until end of turn and when it loses substance, sacrifice it.
When Necromancy comes into play, if it's in play, it becomes an Aura with "enchant creature put into play with Necromancy." Put target creature card from a graveyard into play under your control and attach Necromancy to it. When Necromancy leaves play, that creature's controller sacrifices it.
Does this mean that I cannot cast it during my main phase as an instant? I have been utilizing Necromancy to reanimate Woodfall Primus and such so I get two kills and a creature. But does this errata mean that if I cast Necromancy during my main phase, the Primus would not die at the end of turn? Or can I choose to cast it as an instant even if I could cast it as a sorcery? Thanks in advance for the answers.
