Card Effect Lockdown

A Card Effect Lockdown strategy chiefly involves completely nullifying the opponent's card effects, thus making them rely solely on Monster presence, which can be done away with through attacking. You can approach this situation with a few cards.

The cards below are listed in tier in their respective categories, from highest effectiveness to lowest in a deck themed around lockdown.

Recommended cards that negate Spell Cards

 * Silent Swordsman LV7 (Negates Spells altogether, efficient summoning)
 * Horus the Black Flame Dragon LV8 (Doesn't negate Spells already active, a small bit harder to summon)
 * Spell Canceller (Weaker version of Silent Swordsman LV7)
 * Imperial Order (Is a Trap Card, is negated by Royal Decree and Jinzo)
 * Mechanical Hound (Opponent cannot activate spells if you have no cards in hand, running this card requires deck to have less monsters otherwise you will have a hand)

Recommended cards that negate Trap Cards

 * Royal Decree (No cost, easiest to use)
 * Jinzo (Needs a cost, but has a set of cards)
 * Sorcerer of Dark Magic (High cost. Doesn't negate trap cards already activated or Counter Traps)

Recommended cards that negate Monster Effects

 * Destiny Hero - Plasma (Negates only the opponent's Monsters)
 * Angel 07 (Negates trigger effects and effects that activate in Graveyard)
 * Dark Ruler Ha Des (Only negates cards after they have been destroyed by Fiends in battle)
 * Skill Drain (Is a trap card, can be negated by Jinzo or Royal Decree. Has the potiental to neagte your own monsters' negative effects.)
