Ayzor Qohm, Spark Mentor

Each planeswalker card in your hand has
sparkmorph {2}{u}{b}. (You may cast that card
face down as a 2/2 creature for {3}. Turn it face up
any time for its sparkmorph cost and put a loyalty
counter on it.)
Whenever one or more loyalty counters are put
on planeswalkers you control, each opponent
loses that much life and you gain that much life.
