Mind Siphon

Until end of turn, whenever you cast a spell you
don't own, its owner loses 1 life and you gain 1
life. Add {b}{b}{b}. Transfuse 3. (Exile the top three
cards of target opponent's library. Until end of turn,
you may cast any number of instant or sorcery cards
exiled this way and you may spend mana as though
it were mana of any color to cast those spells.)
"My mind is bleeding. Death is the only way to heal
this wound." - King Ikaros, suicide note
