Porg for Lunch

Buyback {1} (You may pay an additional {1} as you cast this spell. If the buyback cost was paid, put this spell into its owner's hand instead of into that player's graveyard as it resolves.)
As an additional cost to cast Porg for Lunch, sacrifice a token creature or a creature with "Porg" in its name.
You gain life equal to the sacrificed creature's toughness times two.
