Well-Deserved Rest

Kicker {u}{w} (You may pay an additional {u}{w} as
you cast this spell.)
Return target creature you control to its owner's
hand. You gain life equal to that creature's
converted mana cost. If Well-Deserved Rest was
kicked, exile that creature instead, then at the
beginning of your next end step return that
creature to the battlefield under your control
with a +1/+1 counter on it.
