Watt Breakdown

Watt Deck Guide: How to Play

Playstyle and Win Condition

Watt Cards

The entire strategy of the Deck revolves around making the Watt monsters attack, trigger their effects to Special Summon again, then attack again. What makes this work is that the archetype can attack directly, even with monsters on the field.

The key monster here is Wattcobra, which in a combo would then use its effect to summon Wattuna. Afterwards, its effect lets it Special Summon a Watt Synchro Monster during the Battle Phase. Wattgiraffe just ensures the opponent cannot activate effects as you attack.

Wattkyuki is the boss monster frequently summoned for the combo and win the game, but Watthydra and Wattchimera provides card advantage over the opponent.

Two crucial Spell Cards to get "Watt" monsters ready are Wattkingdom, which provides a Special Summon at the cost of some LP, and Wattcastle discourages attacking those monsters lest the monsters that attacked them lost 1000 ATK.

Support Cards

Because of how important battling is for this Deck, cards that support this playstytle are rather unique. Luminous Spark is the essential Field Spell for this Deck as the ATK boost adds up for every "Watt" monster that attacks. Photon Sanctuary can be used either to attack, or an easy way to summon Hip Hoshiningen and further give LIGHT monsters an ATK Boost.

Original Bamboo Sword does not give a further boost, but a monster equipped with this card can clear out all monsters the opponent controls.

Super Polymerization has to have the proper materials on the field to be used and clear the way for the "Watt" monsters.

Extra Deck

The Fusion Monsters in the Extra Deck are mainly for the usage of Super Polymerization to get rid of a couple of monsters. Mudragon fo the Swamp and Garura are classic choices, and Starving Venom Fusion Dragon is to deal with the DARK monsters that are dominant in the meta.

Xyz Monsters are scarce but they are in this Deck Recipe for some defensive options. Bagooska is great for stalling the game until you have the right cards, and Evilswarm Exciton Knight can wipe the entire field if the opponent has more cards on the field than you.

For more advance plays, ZEUS and TY-PHON are great for keeping the opponent in check for monsters present.

Hand Traps

Three classic Hand Traps should be enough as this Deck likes going second for the access to the Battle Phase. Maxx "C" and Ash Blossom are mandatory, and Triple Tactics Talent deals with the opponent using their own copies against you.

For combo-centric Decks that swarm the field, Nibiru, the Primal Being can clear their entire endboard in one fell swoop.

Boss Monsters

	Wattkyuki
	Wattkyuki is often the last or second-to-last Synchro Summoned monster you'll be bringing out in a standard "Watt" combo. When it manages to attack, it shuffles materials from the GY and Field to the Deck to Synchro Summon a different "Watt" Synchro Monster, so that it can launch another attack for game.
	Wattchimera
	Wattchimera also shares the ability to attack the opponent directly, even if monsters are on the opponent's field. Once it deals damage, it spins back a random card from their hand back to the Deck, decreasing the opponent's card advantage by just a little.
	Super Starslayer TY-PHON - Sky Crisis
	Unlike its counterpart in ZEUS, Super Starslayer TY-PHON - Sky Crisis can use a single monster as material to Xyz Summon this monster. The only caveat is that the opponent must have Special Summoned two or more times in this turn or the turn before. It can bounce back a monster the opponent controls once per turn.
	Starving Venom Fusion Dragon
	With Super Polymerization in the Deck, and DARK monsters everywhere, Starving Venom Fusio Dragon can be quite a wall to summon. It enjoys an ATK boost if there is a Special Summoned monster on the field when this card is summoned, and it can take on the effect of another Effect Monster on the field.

Watt Counters: How to Beat

Best Decks to Use Against Watt

Floowandereeze

Floowandereeze completely messes with Watt Decks in two different ways. First, its boss monster Floowandereeze & Empen prevents monsters in Attack Position from activating their effects, which Watt monsters need to be in order to Direct Attack.

Second, most of their floodgates deny the Graveyard, and prefers their cards to be banished instead. "Watt" Decks need the GY for their Synchro Summons and recycle effects.

Floowandereeze Deck List & Card Guide

Kashtira

Another floodgate-heavy Deck to deal with, Kashtira is especially dangerous once Arise-Heart hits the field and forces all cards sent to the GY to be Banished instead.

Even more dangerous are the Main Deck monsters that punish the opponent when they activate monster effects. Fenrir and Unicorn need to be dealt with first before launching Direct Attacks.

Anti-Meta Stun

No other Deck can grind out the game more than the Anti-Meta Stun Deck. If it manages to find a way to interrupt the opponent with negates, card destructions and interruptions, it will completely mess up a Watt OTK attempt with ease.

Best Cards to Tech Against Watt

	The Dark Door
	The Dark Door is a niche Continuous Spell as this card restricts the opponent into attacking with only just one monster per turn. Not all Control Decks run this Spell Card, but this means that a usual "Watt" combo when it launches a Direct Attack cannot continue as all other monsters after the first one that attacked cannot attack.
	Mirror Force
	This Deck is super aggressive, meaning it does not have any counters for card destruction effects. The best one against this Deck as it needs to attack is Mirror Force, which will wipe out all the "Watt" monsters in Attack Position if even one of them launches an attack.
	Summon Limit
	A normal "Watt" combo will have multiple summons in order to do its Direct Attack OTK. Summon Limit will limit both players to two overall summons in a single turn, and that will stop the combo even if the requirements are met.
	Battle Fader
	Another threat against this Deck is a niche hand trap: Battle Fader. It can only activate from the hand when a Direct Attack it launched; this card Special Summons itself from the hand, and immediately ends the Battle Phase. Against a "Watt" Deck, that means their combo is immediately stopped.
	Threatening Roar
	Similar to Battle Fader mentioned above, Threatening Roar stops the "Watt" combo well before it can truly begin as it prevents the opponent from attacking the turn this Trap is activated.
