Hallo!
I'm here for some clarification of rules regarding Sectarus casting spells on a target with Nullify or Reverse Magic.
Does Sectarus's curse spells negate Nullify's and Reverse Magic's effects?
If yes, I can understand that Reverse Magic cannot redirect Sectarus's spell because Sectarus is not a valid target, but what about Nullify? And, does Reverse Magic still get to counter it?
I couldn't find the answer anywhere, so if this question has been answered before, I'm sorry.
In my opinion, Nullify would be resolved normally.
Reverse Magic is a little trick because [mwcard=FWQ09] Sectarus, Dark Rune Sword[/mwcard] may not be a valid target.
From the FAQ:
"A spell fails and is canceled, if either of the following occur before the Resolve Spell Step:
1. The target of the spell is no longer a legal target, or..."
In my understanding, when you reveal Reverse Magic, you are the new controller of that spell, if that spell hasn't a legal target; then, it is cancelled.
Currently, as far as I know, there are no Enchantments that target Equipment. Therefore, any Enchantment cast by Sectarus would be cancelled with Reverse Magic.
Cheers
