(Spheres of Power) Building a Lord of Change?

[FortuneXVI]

I'm going to play in a high end Warhammer Fantasy-themed game of Pathfinder soon. We start at level 20 Gestalt, and we're using spheres of power in lieu of vancian casting, so I thought I'd make a lord of change...any idea what classes/talents are best to recreate our feathered friends?

I'm not all that familiar with 40k, but after chatting with some friends for a bit to get the gist I would suggest a Fey Adept if you want to focus on the illusions and mental side of things or the Shifter if you'd rather be primarily a shapeshifter. In both cases you'll want to invest primarily in Alteration, Illusion, and Mind, maybe grabbing Divisive Totem from the War Sphere for added discord-sowing.

If you want to really lean into the chaotic nature of 40k's warp magic, Wild Magic feats and the associated drawback+boon can offer some added power at the cost of potential backlash in the form of random additional effects
