Trusted Advisor - {1}, {t}: Target player gains 3
life, exile the top 2 cards of their library face
down. For as long as those cards remain exiled,
you may play those cards and you may spend
many as if it were mana of any color to cast
those spells.
Whenever you cast a spell you do not own,
each opponent loses 1 life and you gain 1 life.
Things aren't always what they seem. ~ Jafar
