Pixie Sorcerer

When Pixie Sorcerer enters the battlefield, each
player searches their library for a nonland card
and exiles it. Whenever Pixie Sorcerer becomes
tapped, until end of turn you may cast a card
from exile and you may spend mana as though it
were mana of any color to cast it.
{4}{w}{w}, {t}: Put two +1/+1 counters on Pixie
Sorcerer. The next time you would lose life this
turn, instead you gain 2 life.
