Questions about Koth

A couple of questions:
When using Koth, Fire of Resistance, are mirran mountain tokens considered to be land supports? And is there a way to increase their level besides when using Geomantic Uprising? I mean, I'm still gonna get him and use him extensively. Koth of the Hammer has always been one of my most frequently used planewalkers and this new one can now have up to 6 supports. I think this the start of a wonderful friendship!
