When Shaman of the Pack enters the battlefield and there's already another Shaman of the Pack on the battlefield, does the card's ability only trigger for the one card entering the battlefield? Or does it trigger for both the card entering the battlefield and the card on the battlefield? I ask because the rules text on the card does not state "When this card enters the battlefield..." It specifically states, "When Shaman of the Pack enters the battlefield..."
For instance, I had four Elf creatures on the battlefield: a Shaman of the Pack, a Wren's Run Vanquisher, a Glissa the Traitor, and a Llanowar Augur. I then cast another Shaman of the Pack. As the new card entered the battlefield, should my opponent lose 5 life as the new card's ability is triggered? Or should my opponent lose 10 life as the new card enters the battlefield, triggering the ability of both the card entering the battlefield and the ability of the card on the battlefield?
It just triggers for itself.
A card referring to itself by name just means "this card/creature/etc."
If a card cares about its name or other cards with a specific name it will call out "card(s)/creature(s)/etc. named CARDNAME".
