This Letter proposes a new class of x-ray lasers that lase on several 4{ital d}{r arrow}4{ital p} transitions ranging from 23 to 80 A in Ni-like ions with atomic number {ital Z}=72 to 90 and are resonantly photopumped by Ly-{alpha} radiation from corresponding H-like ions with atomic number ({ital Z}{minus}21)/3. This scheme is unique in that it consists of a family of resonant pairs working off the ground state of the laser ion. Calculations of the gain of these laser transitions in steady-state equilibrium plasmas are presented.
