Fortalece 3. (Elige la criatura con menor resistencia entre las criaturas que controlas y pon tres contadores +1/+1 sobre ella.)
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.
