Power creep! /s

Given the existence of Arcane Sanctum and Nomad Outpost and whatnot, I figured it might be within possibility to do gate versions.

It is kind of power creep though.

Another temptation/route is to make them legendary, maybe rare, and maybe add nonbasic landcycling.

The flavor these cards refer to is something of a rather legendary nature. I could just make them legendary to counteract them being gates.
