Spellcaller

Magecraft — Whenever you cast or copy an
instant or sorcery spell, gain 1 life. If this ability
has resolved four or more times, instead draw a
card and gain 1 life.
Vigilance
I distinctly remember it's haunting cry as the sun rose
over our camp. It was like the mana listened and
obeyed.
