For my teaser trailer I will be using Montage editing, this is because I want my trailer to be fast paced and the shots to quickly change. It is defined as "the juxtaposition of such successive shots as a cinematic technique whereas continuity a style of editing marked by its emphasis on maintaining a continuous and seemingly uninterrupted flow of action".
As my trailer is of a party scene, I want the pace of the trailer to be fast. I can achieve this with quick cuts via montage editing.
