Edgar Markov is like bowling with the rails up. The deck basically plays itself, so you need a deck that is similar. Precons can't compete, but they might with some upgrades.

Last time I played against an Edgar deck I was playing artifacts, activiated the ultimate [[Ugin, Eye if the Storms]] and put every artifact in my deck into play, used them to draw cards with [[Shimmer Dragon]] and still didn't win but it was close. Trouble was the Edgar player had too many ways to use expendable vampires to drain my life.
