I've been looking over "The Shining Darkness" and found 2 cards that will kill Lightsworn decks.
Ally of Justice Core-Destroy
DARK/Machine - Effect/3/1200/200
If this card battles with a Light monster, destroy that monster without applying Damage Calculation.
Crack to the Different Dimension
Normal Trap
Activate only by declaring 1 attribute, and both players select monsters [...] of the declared attribute in their respective Graveyard. Remove the selected monster(s).
EDITNo longer Lightsworn killers. Still they're not too bad, I may still side Crack.
