Not every PvP box is needed; some have backrow staples, while others contain archetypes for specific decks.
Effect negation is the flavor of the month. Countermeasure against strong staples such as Vision HERO Vyon, Amazoness Princess, and the Fur Hire swarm trio.
General purpose battle staple. Considered an upgrade to Mirror Wall for its permanent stat reduction, maxing out at 2400 ATK down. Especially strong against swarmers like Fur Hires.
Contains the core Hazy engine, with Sphynx being found at the Card Trader.
Good for decks that rely on having a frontline presence, such as Geargias or Aliens.
Unique anti-backrow in that the pinned card cannot be chain activated, locking it down for good.
Cut the momentum from decks such as Masked Heroes or Fur Hires. Returns as frontline fodder on other Trap usage.
Sent Amazons from burn deck accomplice to KoG overnight. There's a reason it's limited to 2 copies.
Easy to summon for Trap-heavy decks such as Amazons. Very important in their mirror matchup for the full backrow wipe.
Contains Anki and Mask Change which propelled Destiny Heroes out of meme tier. Combined with the Destiny Rulers structure deck, Valiant Souls makes Masked Heroes a top tier deck.
Hands down the most powerful card in Duel Links; double monster destruction for no cost other than the card itself. Will singlehandedly win you games as long as your Graveyard is Trap-free. Even with this restriction, it's worth running multiple TTH copies just to increase the chance of starting with such a powerful effect.
Tribute fodder for decks like Hazys.
