Greed Subdomain and a Drow Noble

[Paradox Fate's Traveler]

Hey im building a Drow Noble Cleric.
I encountered a interesting subdomain ability that might work out well with the Special abilities a Drow Noble.

More for Me (Su) (Trickery Domain)
When another character within 30 feet casts a spell with a range greater than touch, you can attempt a caster level check as an immediate action (DC = 15 + the spell’s level). If you succeed at the check, you receive the spell’s benefit instead of one of the spell’s intended targets (chosen by you). If you are already a target of the spell, you are affected as though you were targeted by the same spell twice (which may or may not benefit you; remember that bonuses from the same source do not stack). This ability does not grant you knowledge of the spell being cast. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

Drow nobles can cast dancing lights, deeper darkness, faerie fire, feather fall, and levitate each at will, and have detect magic as a constant spell-like ability.

so could i see the spell school a spell belongs to before i use the domain ability or is it still i wont know till it hits me?

i think mainly they ment you need other methinds (such as using spellcraft) to identify the spell while it is being cast.

also note drow nobles at that power level (if allowed to start noble or took all the drow feats to become one) also have spell resistence . youll need to lower it beofre stealing a spell or it might prevent you from gaining it.
