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.
Cards you should get
Dark Magician of Chaos
★8/DARK/Spellcaster/ ATK 2800/DEF 2600
During the End Phase, if this card was Normal or Special Summoned this turn: You can target 1 Spell Card in your Graveyard; add it to your hand. You can only use this effect of "Dark Magician of Chaos" once per turn. If this card destroys an opponent's monster by battle, after damage calculation: Banish that opponent's monster. If this face-up card would leave the field, banish it instead.
Activate this card by targeting 1 Normal Monster in your Graveyard; Special Summon that target in face-up Attack Position. When this card leaves the field, destroy that monster. When that monster leaves the field, destroy this card.
Send 1 Level 4 or lower Normal Monster from your Deck to the Graveyard, and if you do, add 1 monster with the same name as that card from your Deck to your hand. You can only activate 1 "Painful Decision" per turn.
I've finally decided to spend gems on this pack. Great backrow support with Wall of Disruption to replace Mirror Wall; and Draining Shield for Mill, Amazoness Sword Woman or Mausoleum decks.
Painful decision is a great addition in my casual decks : Magnet and Ojama. I also has its place in my Frost and Flame Dragon deck, in order to send WATER and FIRE monsters to the graveyard. And of course, a great addition in a Pyrorex-based deck.
Birthright is great in any Buster Blader fusion deck. Too bad I only have one copy.
Finally, I feel like Ice Counters will be part of the next meta ;).
Concerning Man-Eater Bug... So much noise for nothing : I've only met one in PVP for now.
It should be 7 imo.
The SR/UR contain generic usefull cards in WoD and Chalice, also some support for certain decks like Birthright, DS, MEB, and Painful Decision. Its also a minibox so cheaper to buy. That said,the rest of the cards(exp. the R/N ones) is just awful. Moreover it doesn't have core cards to make proper deck, unlike the last 5 box so its not really a good box to start for new player
