Tome of Wild Imaginings

When a player casts a red spell, gain 1 life.
When a source deals non-combat damage, each player exiles the top card of their library. Until end of turn, you may play the first card exiled with Tome of Wild Imaginings each turn.
Bound in leather from dream serpents, the tome glows with inspiration. With each turn of the page it stirs the soul of any who read it's tabooed text.
