-Great synergy between the light and dark monsters.
-You are constantly drawing and have outs for any card on the field.
-The bystials and black/white dragon allow for a turn 1 extra deck lock with seal/branded lost at a very high constinstancy rate.
-The red dragon allows you a second turn play with your buster dragon before it expires.
-Branded lost and cosmic clycone help stop runick
-Black luster and chaos emperor are really a late game/last resort usually for getting rid of a stubborn card.
