Some of the wording on cards is being changed to be more clear regarding the difference between "playing a minion" (which means played from your hand), and "summoning a minion" (which takes into account anything card that says, "summon a minion" including minions played from the hand).
Knife Juggler falls into the latter and reads, "After you summon a minion, deal 1 damage to a random enemy." Totems count as minions, so they would also count for this ability.
