I know this tactic is mega old but just in case...
The tactic requires you to get 2hkoed as fast as possible and make up points with the losing streak bonus.
Because you lose very quickly you can get 2 loses faster than a normal win...
20 points for a loss + losing streak bonus:
2 defeats: 3 pts, 3 defeats: 6 pts, 4+ defeats: 12 pts
other variations: If you want at the end of the deathmatch you can get the come back bonus + a win to give you a 65 point bonus.
problems: idiots in DM who timeout on you or play slowly...
Also people who play you twice or more times as they build up streaks and get perscution bonus'
Also this will effect your win/loss ratio.
Still though you can get a good amount of points with no effort .
Here's an example deck of "No Effort Deathmatch"
