Nightward Guide

Phasing-Soulbond (The soulbond does not break while Nightward Guide is phased out, but neither of
the paired creatures get to benefit from soulbond unless Nightward Guide is phased in.)
As long as Nightward Guide is paired with another creature, both creatures are unblockable and have hexproof.
