Card Rules: Rulings powered by The Netrep API. Discarding 1 Spell Card is a cost to activate this effect. If you activate the effect of 'Chiron the Mage' , then flip it face-down then flip it face-up all in the same turn you can activate its effect again. The restriction that you can only activate this effect once per turn is a condition not an effect. So if 'Skill Drain' is on the field you can pay the cost once per turn (for no effect) but not pay the cost continuously in the same turn.
