For Deathmatch Type 1 - Rescue works really well...I don't really like playing DMs but I played a couple with the Alec Cr + Marco combo and did quite well. Thank whatever deity you believe in that you don't need to impress a couple of douches by using decks that do not fit the bill for deathmatch, and just use a deck that will get you the most points you can, since that is the whole purpose of the DMs.
For Type 2 you can use any clan really...but Sentinel and Bangers can build some heavy hitting mono-decks, which are quite easy to score high with. Nightmare works quite well too.
