How does Bottled Vortex work: where can I destroy cards from, and when do I draw?

Question

Accepted Answer

Destroy up to two cards from your hand or discard pile, in any split such as one from each, before drawing. The cards are destroyed, not discarded. Once played, Bottled Vortex is no longer in your hand, so an effect that needs it in hand, like Agony Field, cannot target it.
