Conveniently, in new World Of Darkness, the powers of mages stem from a single source: a persons connection to one of the five supernatural watchtowers. That grants them access to all magic, with their tower affecting their method of approach to magic as well as their natural strenghts and weaknesses.
A connection the the watchtower of the Leaden Coin (Superior arcana of Death and Matter, inferior arcana of Spirit) or the watchtower of Lunargent Thorn (Superior arcana of Time and Fate, inferior arcana of Forces) would be especially nice. At best, Matter arcana is akin to Fullmetal Alchemist transmutation, at range, at will, irrespective of target's composition and mass before and after transmutation (with the exception that you can't effect living matter without also some skill in the Life arcana)
For example, you could with the blink of an eye transmute the gun an enemy is holding into nitroglycerin...Not to mention all other cool stuff you can do with it even without a complete mastery. Death... well, think more common necromancy, and summoning, compelling and speaking to the dead (want to know what Mozart though on his deathbed? Let's find out!).
On the other hand, time and fate manipulation to the degree where you can make an alcoholist go cold turkey and become the best free clinic doctor within 400 miles, or simultaneously and instantly view all the immediate effets of your actions and the results and then simply select the best future out of them to have actually happened retroactively in the future... is simply insane. Think of it this way: cornered in a house, with an assasin about to shoot you? See what series of actions on your part (and your opponents consequent actions) result in him dying and you fleeing as unharmed as possible, then choose that future and it already happened just like the way you foresaw;you effectively saw the past from the viewpoint of almost infinite possible futures, then selecting which future realized.
So yeah, connection to a nWoD Mage The Awakening watchtower.
