Yu-Gi-Oh: 10 Most Powerful HERO Cards
2. Masked HERO Dark Law
Dark Law is good. Dark Law is SO good that people who don't play HERO decks play him.
Despite a middling 2400 ATK, Dark Law has in him two effects that would, individually, be up for debate by the Geneva convention. The first forces your opponent to discard a random card any time they add cards to their hand outside their normal draw. That can be painful, especially considering how many cards let you add to the hand these days. Even the most broken card of all time, Pot of Greed, would be wounded by that ability.
The second ability is the deadlier of the species, locking off your opponents GY in favour of banishing all their cards instead. For most modern archetypes, this is a death sentences, as they focus so heavily on sending cards to and from the GY. Even Shaddolls, almost designed themselves to shut down HERO decks, would be crippled by this.
Coupled with Mask Change II, which lets ANY Dark deck play this demon, Dark Law is not just the most feared of the HERO cards, but among the msot feared of all cards.
