Do you have Toro and/or Chiara? Dolly is more viable than Snowflake but neither really belongs in DM. If you have these other options, you could try to form a 4-4-4-3-3-3-2-2 config if you aren't satisfied with the current one.

Snowflake to chiara and Dolly to Klawz

Seems pretty good, but you are a bit short on ATK manip and/or cards that can force the opponent to pill - perhaps Arkn for zer0 dead?
having such cards would be useful to bluff/win rounds without having to pill.

I disagree with the DR comment left on the preset, IMO the deck looks great the way it is.

DRs do slow DMs, but I take it you want to win more rounds rather than just get through them quickly. Especially with a setup without attack manipulation like this, you will win at most 2 or 3 rounds in the bulk of your matches. This is where the DRs come in, another Praxie/Zeke/Dolly is pointless if your pills are spread too thin for them to even win their round.

How is it doing so far? test it out if you feel you need atk manip then Lorna to Danae

You will start to see more Uppers and junks for sure but if it works keep it as is for now. though Danae would probably be more use vs ghiest then Lorna would tbh
