Blinding Helix

Blinding Helix deals 3 damage to target creature. If Blinding Helix is shifted, it instead deals 1 damage to target creature and you gain 3 life.
Shift {w} (You may cast this spell for its shift cost. As you do, if spells are not shifted, spells cast for the rest of the game are shifted. Otherwise, they become unshifted.)
