Rulings

(11/24/2014)
Bolster itself doesn't target any creature, though some spells and abilities that bolster may have other effects that target creatures. For example, you could put counters on a creature with protection from white with Abzan Skycaptain's bolster ability.
(11/24/2014)
You determine which creature to put counters on as the spell or ability that instructs you to bolster resolves.
