If I sacrifice an Eldrazi Spawn token, will it activate, say, {Butcher of Malakir}'s or {Blood Artist}'s ability? Thank you!!

[Remillo]

Sure.  It's a creature going to the graveyard, which is the definition of Dying.  Because the abilities don't specify a creature card, tokens will trigger it, too.

Ohohohoh!! Thank you!

Please remember to use the curly brackets or the book on the upper right to link cards. It makes it easier to look up the cards. Thanks.
