All-Sky Automated Survey for Supernovae (ASAS-SN) scans the entire visible sky at daily cadence to search for bright transients, especially supernovae. Over the last few years, ASAS-SN has been the most productive survey at finding bright supernovae (<17 mag). Compared to other transient surveys, it is minimally biased toward host properties and has an exceptionally high level of completeness in spectroscopic classifications. I will discuss our ongoing efforts to collect the first volume-limited complete sample of SNe Ia from an un- targeted survey, with the primary goal to test the WD-WD collision models. I will also discuss a few unexpected discoveries of transients thanks to the "organized luck" of our systematic approach.
