Not related to the OP but the Planar Binding spell; it's not a bit strange for a Good Wizard to use such a spell to bring a Good Outsider ? (IIRC, that would give the spell a Good descriptor).
It would. "When you use a calling spell to call an air, chaotic, earth, evil, fire, good, lawful, or water creature, it is a spell of that type."
The problem being, of course, that to hold it, you need a Magic Circle Against [X] spell. And Magic Circle Against Good is an [Evil] spell, Magic Circle Against Evil is a [Good] spell, Magic Circle Against Law is a [Chaotic] spell, and Magic Circle Against Chaos is a [Lawful] spell.... sure, if you're Calling an Archon, well, they all have the Lawful and Good subtypes - so Magic Circle Against Chaos, and you're Good, but you're not okay, as the Archon has clear proof that you serve Chaos (he's stuck in a [Chaotic] spell, after all). That Planetar you were planning on using Greater Planar Binding to fetch a caster that can do a True Ressurection for the Cleric, on the other hand, is "Always good (any)" - in order to Bind it, you're basically stuck with Magic Circle Against Good to hold it (well, if your DM rolls the law-chaos axis, you've got a 2 in 3 chance of having something that will hold it....). Which means you're casting an [Evil] spell, to force a [Good] creature to do your bidding. Is it any wonder these things come out hostile?
Okay, Elementals are usually neutral, and any of the Magic Circle spells will work.... so you haven't done anything direcly opposing their alignment. But still, you trap them and they bargain for their freedom (which is, ultimately, what they get by giving in).
Now, RAW doesn't address what happens if you skip the trap.....but if you do, you're only casting a spell that's in tune with what you're Calling up. So the NG Sorcerer with Magic Circle Against Evil is *probably* going to be okay if he attempts to hire the Planetar, rather than coercing (skips the Magic Circle, skips the Calling Diagram, skips the Dimensional Anchor - and the Planetar is in no way trapped - and my just go back to whatever it was it was doing).
Oh, but if you're going the Planar Binding route? Pick up Moment of Prescience as soon as you can - bargaining is an opposed Charisma check, which Moment of Prescience covers.
