I'm working on a Sponsored Magic for a player of mine who wants to play a trickster archetype. Since we're running in a London setting, he decided he'd like to represent the traditional European trickster Reynard the Fox. Deception is kind of hard to represent as a theme, though, and perhaps a bit narrow, so I decided Reynard could also be somewhat representative of the forests and natural areas foxes live in, perhaps even with some connections to the fae (or being a powerful fae himself). This would give his magic some similarity to Summer Court magic, but with its own themes and twist.
I'm thinking that for evocation, this would give him effectively Wood and Spirit as elements, and for thaumaturgy (possibly at evo speeds), illusions, veils, and biomancy. I'm not sure if that's too broad, too narrow, or just right. Also, most sponsored magics seem to have some additional minor benefit (+1 to power for a certain type of magic, weakening enemy faction's toughness powers, etc.), and I'm really not sure what would be suitable here.
Any input, guys?
