The 7th mini card box: Servant of Kings has been leaked by a JP Yu-Gi-Oh! website. It will be released during mid October.
The box contains an assortment of archetypes and cards that you can simply splash onto any deck. But is mostly composed of Machine types from the newly introduced Machina archetype to new Genex support. Another notable fact is the addition of the neospacian archetype and the very first Neos contact fusion monster in Duel Links.
Who should buy this pack
Definitely buy this pack if you want to build a Machina deck or Genex deck. Other than that many cards in this deck can also be quite useful, Forbidden Chalice is great for dealing with monster effects, Dark Magician of Chaos is really good if you can get him out, and Painful Choice is a great deck search card. Peten the Dark Clown can be used in tribute summon or relinquished decks This pack also contains lots of monsters that can serve as beaters, some are even easy to get R monsters.
