Best use for shadow spells?

[Particle_Man]

I have seen this posted a couple of times in this thread and I'm not sure where it's coming from. All teleport spells are Conjuration (Teleportation) in 3.5, and the Shadow Conjuration tree of spells only covers Conjuration (Summoning) and Conjuration (Creation) spells per the SRD
I'd be interested in knowing how people are reading any of these spells as covering any Teleport spells though...

Shades is different as it says it is like Shadow Conjuration except it duplicates Sorc/Wiz conjuration spells of 8th level or lower (unlike Shadow Conjuration it does not restrict the conjuration spells it can duplicate by sub-type by saying "like Shadow Conjuration except it duplicates sorc/wiz conjuration spells of 8th level or lower of subtypes X, Y and Z", implying that Shades can get you a shadowy version of Teleport)

One example I've seen is using it to duplicate a damage spell of an energy type that a PC might not have access to- like a spellcaster who specializes in electrical spells who is fighting something vulnerable to cold...or immune to electricity.

Or similarly, tossing off a targeted or AE effect spell when you don't have one of the appropriate power available.

In short, its all about flexibility, albeit at a potentially high (spell slot) cost.
