Clown Control decks often revolve around either "Stumbling" or "Labyrinth of Nightmare" as the Deck works differently depending on which is chosen. Builds that use both should focus the deck around one of them, using the other for support purposes.
"Stumbling" lets the player stall from opponent attacks and trigger the effects of "Dream Clown" and "Blade Rabbit", thereby protecting his or her monsters and Life Points while maintaining field presence. The strategy at large is to get any two of a "Dream Clown", "Blade Rabbit" or "Crass Clown" on the field (with one in eachposition) so you can use one to destroy or return a monster, while the other attacks.
Clown control does very little special summoning in relation to most decks, allowing it to use various Anti-meta cards to slow down the opponent and increase field control. These include "Fossil Dyna Pachycephalo", "Jowgen the Spiritualist" and "Thunder King Rai-Oh". Whether to use Fossil Dyna or Jowgen, depends on preference and play style. Jowgen the Spiritualist is faster at getting rid of the Special Summoned monsters than Fossil Dyna, but Dyna is more guaranteed to succeed than Jowgen. Grave of the Super Ancient Organism is another excellent anti meta card, for use against decks that make extensive use of nomi and non-xyz semi-nomi monsters.
Detail on additional tech options
"Don Zaloog" and "Spirit Reaper" can take advantage of the opponent's open field for hand disruption. This is especially useful if the opponent saves their cards in their hand for explosive plays later on.
"Construction Train Signal Red" can be used to protect dream clown from a single attack allowing its battle position to be changed to defense next turn. They can then be used to rank 3 xyz, still leaving the turn players normal summon unused. Alternatively, it can be summoned on direct attack, protecting lifepoints and xyz next turn with a normal summoned dream clown. It can also be used to protect crass clown or flip summon monsters after they have been set. The usage of this card is more difficult to anticipate and stop than regular backrow protection.
Performapal Turn Toad can change change battle positions once per turn, triggering clown effects each turn.
Black Salvo" is used to summon "Karakuri Shogun mdl 00 "Burei"". Its effect can then be used to manipulate positions once per turn, allowing it to attack the same turn it is summoned in stumbling builds. Its effect can also be used to make sure it changes to attack position at the end phase in labyrinth builds. An additional position change and possibly synchro can occur if a "Karakuri Strategist mdl 248 "Nishipachi"" was summoned by its effect.
The deck uses its backrow to trigger effects and slow down the opponent, making spell destruction such as Mystical Space Typhoon, Twister, Galaxy Cyclone and Spell Shattering Arrow an effective counter strategy. Cards with field destruction effects such as Black Rose Dragon and Exciton are also deadly.
