Leyline of Paranoia

Whenever an opponent draws a card, he/she either reveals that card or loses 5 life.
Whenever an opponent casts a spell, you may pay {b}{b} and name a card to look at that opponent's hand. If the named card is in his/her hand, that opponent discards it. Otherwise, you lose 10 life.
A dreadfully suspicious mind is rarely conned.
