Steeme said: Ob Nixlis' unique win condition makes him a priority. Very handy for matches where you avoid playing/spawning creatures. I don't use him in PvP though.
I don't have Koth, but if you're planning to get Nahiri as well I don't know if you'll get much additional value from buying Koth, unless you're planning to use Nahiri on white nodes.

Admittedly, this is kind of a specific edge-case scenario, and more of a comment on the power of one specific card, rather than general-purpose advice, but: if you ever happen to find yourself in possession of Omniscience, Tezzeret 1 instantly goes from being one of the worst Planeswalkers to being hilariously strong and really fun to play.

G2 needs only one card actually, 'Anointed Procession'.This gives him 16/16 every time he uses his 2nd ability, and usually that's enough
