Def, Khantsievth's Guide

Whenever an opponent gains life, you gain that
much life.
Pay X life, Tap an untapped Horror or Minion
you control: Put a guide counter on target
creature with converted mana cost twice X or less.
Then, if it has 3 or more guide counters on it,
gain control of it, and it becomes a black
Horror Minion. (Ir loses all other colors and types.)
