Delif's Sanctuary

When Delif's Sanctuary enters the battlefield,
choose a color. Whenever a creature in play is destroyed by a source of the chosen color,
regenerate it. That source's controller gains life
equal to that creature's power.
{1}{w}{g}: Untap target unblocked creature and
remove it from combat. Its controller gains life
equal to its power.
