How much are you willing to pay in order to save one of your creatures? What about save one of your creatures and destroy one of your opponent's? Ajani's Prescence from Wizards of the Coast's expert "Magic: The Gathering" expansion set "Journey Into Nyx" is a common white instant that can do that and more, for just one white mana.
Ajani's Prescence - W
Strive - Ajani's Presence costs 2W more to cast for each target beyond the first.
Any number of target creatures each get +1/+1 and gain indestructible until end of turn. (Damage and effects that say "destroy" don't destroy them.)
Ajani's Prescence warrants play in limited even without reading its strive ability, after which it becomes an auto include that can save your bombs from removal and have a significant amount of impact on the combat step.
In constructed card in particular to pair with Ajani's Prescence is Battlefield Thaumaturge, which will reduce the strive cost by 1 for each target. That's especially useful if you plan on abusing Ajani's Prescence in a deck filled with heroic creatures such as Battlewise Hoplite, Phalanx Leader, or Fabled Hero.
