Say I have a Tartaros "All demons that holder captures, discards, or has in Land of Bondage are placed in Tartaros. Release one demon to holder's territory from Tartaros when one of holder's demons wins in battle." in play. I block, and my opponent plays a card that says I must discard a card, I know it was his card played, but if I discard a demon from my hand or battle, would my demon then go to my Tartaros?
