Exypnos, God of Twists

Indestructible, Prowess
Exypnos can't attack or block unless it has four or more Quest Counters on it.
Each time you cast a Noncreature Spell, put a Quest Counter on Exypnos.
Noncreature Spells you cast cost {1} less.
{u/r}, Remove Three Quest Counters from Exypnos: Cast target instant or sorcery card from target player's graveyard without paying its mana cost. If that card would be put into a graveyard this turn, exile it instead.
