Archer queen + goblin curse

hey people, does anyone know if the goblin curse stacks with the archer queens damage boost from her ability? ive been trying to test it but its not clear to me. trying to build a deck around it that utilizes its buff

Ive also been testing it with spells and i dont think it boost the spell damage, which i think is lame. but a amp rocket would do over 700 direct damage to the crown tower. anyone else test this?
