Toriel's touch

Preparation (At the beginning of the game or a certain phase, you may put cards with preparation on the battlefield.)
Exile this permanent: gain 10 life and draw three cards or:
if you have 5 or less health, restore your life to
your starting life, draw five cards and gain two
mana of any color in your mana pool.
He's too strong for you, here's some backup.
