Planeswalkers

Like many others, I am trying to collect every original planeswalker card.   I don't  mind paying face value for the playable ones, but have no intentions of over paying for the rest.  I have tons of rtr to trade that I haven't updated yet, so if you need something specific, lmk.

Here are the ones I still need, only looking for non foil versions

Ajani Goldmane
Ajani Vengeant
Chandra Ablaze
Chandra Nalaar
Elspeth, Knight Errant
Garruk Relentless
Garruk, Primal Hunter
Lilliana Vess
Nicol Bolas
Sarkan the Mad
Sarkhan Vol
Sorin, Lord of Innistrad
Tezzeret, the Seeker
Venser, the Sojourner
