Silent Knights

The Silent Knights, also called the Damned Knights in the OCG, are a series of DARK monsters. Their names include "Silent Knight". They rely on powerful effects to stop multiple high ATK monsters and the use of their effects, and their strategy involves preventing a strategy from working. This deck features a new sub-type called Resolve. These cards are Summoned by Resolve Summon.

Play style
This is one of the most straightforward "lockdown" decks built and relatively easy to use because of the synergy between the monsters, it has high overall flexibility. Also, cards like "Royal Decree", "Jinzo" and "Magic Jammer" are needed to prevent your opponent from activating any Spells and/or Traps. "Gravity Bind" and "Level Limit - Area B" work great with this deck.

Weaknesses
"Silent Knights" aren't very fast, but once they do get the ball rolling, it is hard for a deck not loaded with field destruction cards to stop them. A deck that can maintain a good field presence might be able to stop these monsters, since they have low stats. Also, anti-DARK cards, like "Shadow-Imprisoning Mirror" or "Consecrated Light", are very effective against the Archetype, though some Spell and Trap destruction helps. "Silent Knights" are currently a very effect-reliant Deck. Without their effects, they are pretty much useless. However, they can easily stop decks with their abilities. "Silent Knight Balan" and "Silent Knight Balin" can lock down your opponent's attacking options, as well as Special Summon themselves when your opponent Special Summons a monster, while "Silent Knight Mordred", one of the few offensive forces of the Archetype, gains ATK and DEF whenever a monster on your opponent's side of the field gains ATK and DEF. Cards that can counter the activation of effects, like "Effect Veiler", are very useful in this deck.

Trivia

 * The Silent Knights are mostly based on evil knights of mythology, like the Nazgul, as well as villains from Arthurian lore, like Mordred and the brothers Balan and Balin.
 * The Holy Knights have counterparts, the "Holy Knight", which, when combined with the Silent Knights in the TCG, are a pun based on the Christmas carol, "Silent Night".
