I disagree. Duel Law can be useful, but it's situational. It only works for 2 cards in the Deck, and those are easily removable by Spells.

Battle Aura Circle is great for protecting your Life, but I tend to use it for monsters usually. I guess it's just different experiences with the card.

Double Guillotine isn't all that from my testing. Against Danger World? Hill Yes! Dragon World? Occasionally. Magic World? Never. Where as Destruction is more overall usable and not dead against one of the 3 decks in this game.
