[Spheres of Power] Building Planeswalkers

[Vhaidara]

So, after seeing this (https://www.youtube.com/watch?v=x-tf-IK9R7k), I kind of want to build the core force of planeswalkers.
Jace
Chandra
Leliana
Gideon
Garruk (the real green planeswalker)

For Chandra, I'm thinking an Ifrit for race (the image on the PFSRD is almost perfect for Chandra), but i can't decide between Elementalist or Incanter. She's definitely Cha based (pure instinct and emotion), and she focuses on the Destruction sphere, but with Incanter you can also splash in some Nature (fire goemancing), Alteration (hey I'm on fire), Conjuration (probably her Phoenix), and Warp (Planeswalker)

Any other opinions?

Good idea, but I recommend not taking alteration, and maybe take Protection instead. I would say the on fire bit is more of an advanced racial thing, whilst the protection from fire is a good idea.
