Wandering Spirit
Reveal the bottom card of deck. If it is a demon, put it in your territory. May band to a generic demon. If your demon is discarded, place it beneath deck instead. Cannot be negated.

Seven Wicked Spirits
You may interrupt all Fortresses and exchange this Evil Character with any other Evil Character in play or set-aside area.

Seven Wicked Spirits has two main issues: First, it's negatable, which is a major factor that should always be considered when there's a discrepancy. Second, your opponent isn't going to always have fantastic ECs in territory, so it can end up being a dead card for several turns in a row. These factors contribute to it being a risky card to splash, so it doesn't really see much play. Wandering Spirit is the touchstone of a demon defense, and while demons aren't great right now, they're better than SWS.

He can really only band to Spirit of Temptation, or, well, SWS.

Or Trembling for infini-blocking.  Or Legion to be mean.  Or other generic banders (besides Spirit).

But being able to keep coming back by putting all of your discarded demons below deck is the best part, especially when I use the chain to take your EC and play my DoU or BB, for instance.

They really shine in T2, but they are still useful in T1.

I didn't mainly use SWS to switch for an opponent's character so their defense was irrelevant but rather as a way to deal with their fortresses like the temples. 

As useful as I found sws, the CBN of WS to band and recur is I think more reliably strong.  I like using SWS in a lot of defenses but I wouldn't use a demon defense without WS.

This doesn't actually work. The fortress interrupt lasts only as long as the ability does. Once the exchange happens, forts kick back in.

Ok, you missed how to play it (or they changed the rules so 50/50). 

Yes, the interrupt stops and the fort kicks back in but only after SWS's ability resolves completely.  This is like banding chains; the umbrella interrupt covers not only the exchange but also the abilities on the exchanged character because that is part of the exchange.  Back in the days of Z-temple I would frequently do something like:  block with sws, interrupt their Wall of protection and Z-temple, exchange with my Gomer, band to their demon, band to my Namaan with horses, play snare and capture their hero before their forts and protection kick back in. 

In fact, before the existence of ASA it was one of the best ways to deal with forts.  I think still amazing but the prevelance of negating abilities with heroes and Cov w death make it not as good.

It was pretty effective back then but in my last post I agreed with you about now which is why I voted for wandering despite my love of combo plays.
