Diplos, God of Inner Struggles

Indestructible, Lifelink
Diplos can't attack or block unless it has four or more Quest Counters on it.
Each time you gain life, put a QC on Diplos.
At the beginning of each Upkeep, target Creature gains Lifelink until end of turn.
{w/b}, Remove 3 QC from Diplos: Each opponent discards their hands and lose life equal to the total number of cards discarded. You gain life equal to the total cards discarded.
