Мгновенное заклинание
Уничтожьте целевое атакующее или блокирующее существо. Подмога 1. (Выберите из существ под вашим контролем существо с наименьшим значением выносливости и положите на него один жетон +1/+1.)
You determine which creature to put counters on as the spell or ability that instructs you to bolster resolves. That could be the creature with the bolster ability, if it’s still under your control and has the least toughness.
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 Aven Tactician’s bolster ability.
