In the past three years, there have been 5 optical alerts during good weather conditions and reasonable declination of the source. Three alerts have resulted in discoveries of VHE gamma-rays from previously undetected sources. In this paper we discuss the discovered sources, MAGIC observations of BL Lac and 3C 279, and we give an outlook for ToO observations of blazars with MAGIC in the MAXI era., Physical characteristics: Original contains color illustrations, Elina J.
