All Main Deck "Mekk-Knight" [[Effect Monster]]s share the following effect:
* ''"If 2 or more cards are in the same column, you can Special Summon this card (from your hand) to that column."''
Thus the archetype relies on Special Summoning high level monsters while there are two or more cards in the same column to swarm the field and generate hand advantage. "Mekk-Knights" has a Kozmo Town-like recovery method in the form of "[[World Legacy Key]]". The Field Spell is very powerful against Extra Deck reliant Decks; but otherwise fares poorly against Deck (or Deck variants) with no Extra Deck monsters such as Kozmo, Monarch, BLS, Nekroz, or True Draco and is resource-intensive.

<!--This is not an exact Decklist. Please do not add multiples or staples.-->
* Cards that prevents the player from Special Summoning can hurt the Deck's capability to swarm. Examples include the "[[Vanity's]]" series, "[[Archlord Kristya]]", "[[Heat Wave]]", etc.
* "[[Ally of Justice Catastor]]" can instantly destroy this archetype's monsters since they are all LIGHT monsters.
