Just to throw some ideas around.
1. Scarlet Lily SS
The turn you send your unit to the cemetary, play Game Over so the SS will bitter destiny opponents L3 & under cards.
Maybe next turn follow up with Crest Spy for a probable iczer chance.
2. Milling Field Wipe
Play cards like Crest Devil Knight, Lelein , and Chaos Absorption to get opponents field down to the last copy of all his units and then Game Over.
3. Curse on World
Play a high LP file (preferably with Broken Anna) to stall the game out until opponent has many units on field, Game Over, and follow up with Curse World to drain SP from dying units last turn.
What other ideas do you have?
