Cleric Class

If you would gain life, you gain that much life
plus 1 instead.
{3}{w}: Level 2
Whenever you gain life, put a +1/+1 counter on
target creature you control.
{4}{w}: Level 3
When this Class becomes level 3, return target
creature card from your graveyard to the
battlefield. You gain life equal to that
creature's toughness.
