I'm gonna go with D&D schools and choose Evocation [http://www.dandwiki.com/wiki/SRD:Evocation_School]... I suppose with the schools you outlined, it could be considered a mix of destruction, telekinesis and elementalism.
**edit**
In case you're curious, the D&D schools of arcane magic [http://en.wikipedia.org/wiki/Magic_of_Dungeons_%26_Dragons#Arcane_magic] are as follows:
-Abjuration: protective spells, mostly... but also counter-spells and such.
-Alteration: spells which change the properties of their targets, such as increasing a man's strength, allowing him to breathe water, or turning him into a rabbit. Also, turning stuff into other stuff.
-Conjuration: spells which summon/transport something, usually from another plane of existence.
-Divination: spells which acquire information, or determine the truth behind things.
-Enchantment: mind-affecting spells, mostly. Sleep, charm, that sort of thing.
-Evocation: Energy-based spells, essentially anything that creates something from nothing... whether that be an invisible hand or a bolt of lightning.
-Illusion: Sometimes mind-affecting, sometimes light-manipulating, sometimes making a solid form from light... in every case, it makes people see things that aren't (or at least weren't) there.
-Necromancy: any spell involving death or the manipulation of life-energy falls into this school, from raising skeletons to healing.
