When casting this spell X must be your
opponent's hand size.
Your opponent discards there hand. If cards discarded this way would be put into the graveyard put them in the zone instead.
(The zone is a second graveyard. Cards that target the graveyard don't affect the zone. The zone is shared by both players. You may only cast cards from the zone if an affect says so.)
You may cast a card from the zone this turn.
