The many faces of Delver.

So with the passing of PT Honolulu we now have at least two different variants of the Delver of Secrets deck. The two being; Mage-Blade and Lingering Spirits. Which one do you guys feel is the strongest, and which deck you feel has the best shot at winning in any given meta. Because, the number one thing I think that is easy to forget is that our FNMs aren't PTs, so when we play a tier one deck the results aren't always what we were expecting. For reference the two decks are:

Spirits! I am already on the band wagon after playing it a little bit. It is really strong. I still love Geist Delver, but....Lingering Souls is borderline broken.

That's how I was feeling about it after seeing it go off during the PT
