The archetype's main strategy is almost entirely based on tightening their defense and loading the Graveyard, since most support for the Gusto archetype requires 2 or more Gusto monsters to be shuffled into the Deck. The Deck relies on heavy defensive tactics, beginning with its trio of searchers which form what Duelists refer to as "the recruiter loop": "Winda, Priestess of Gusto", "Gusto Gulldo" and "Gusto Egul." These three cards can continuously search one another out of the Deck when destroyed in battle while simultaneously filling the Graveyard for other Gusto monster effects. For example, "Caam, Serenity of Gusto" can shuffle 2 Gusto monsters back into the Main Deck in order to draw a card, and "Musto, Oracle of Gusto" can shuffle 1 Gusto monster into the Deck and negate various monster effects.
"Reeze, Whirlwind of Gusto" allows you to forcibly exchange 1 Gusto monster you control for one monster your opponent controls of your choice by sending a card from your hand to the bottom of the deck. Use one of the Gusto searchers mentioned above (except "Winda" due to its wording), in order to boost your Field Advantage and reduce your opponent's. Besides Reeze, cards like "Creature Swap" and "Mystic Box" can also be used for similar purpose. Many players regarding "Creature Swap" as the deck's true staple, since this deck's major plays usually revolving around this card.
"Windaar, Sage of Gusto" is a monster with 2000 ATK that can Special Summon from the graveyard any level 3 or lower "Gusto" monster whenever it destroys a monster in battle. Unfortunately, it is Level 6, making it somewhat problematic to Summon. You can use "Gusto Codor" and "Gusto Thunbolt" to soften the cost of both Windaar's and Reeze's Summon, and set up plays in conjunction with Reeze.
"Gusto Griffin" is the most unique among all Gusto monsters; its effect doesn't trigger when it is destroyed by battle or card effects, instead it will triggered when it is discarded from your hand. In return, it can Summon any Gusto monster from your Deck (once per turn). While the normal Gusto decks have difficulties from using this card, there's a hybrid versions of this deck that can unleash the full potential of this card efficiently.
Overall, Gusto Decks are naturally passive, having a resilient defensive strategy and great recycling/draw power. With the right build, however, they can surprise an unwary opponent with little effort (especially against aggressive-type Decks).
Duel Terminal Storyline
A tribe that lives with the wind and worships the bountiful land they’ve lived on since ancient times. Against their various outside enemies they link their hearts together with and battle along animals that live around in order to protect their land through the generations. However, the Steelswarms started to take over the surface land. So, the Gustos united with the other clans to create a temporary union lead by Vylons. They obtained new powers to fight back the Steelswarms. Soon, the union finally defeated the invaders, but conflicts haven't lowered yet; the Vylons decided to stop the wars between clans — by exterminating them completely. Later, the Gusto teamed up once againwith the other clans in order to cease the Vylon's actions.
After stopping the Vylons, the union between the tribes disbanded. At the time, Gusto tribes were in danger of being attacked by the Gishkis (with goals to claim all the Mist Valley's resources by themselves for their rituals). Fortunately, the Gem-Knights foresaw this, and they lend their powers to protect Gusto tribes from danger. After the lswarms appeared and threatened to destroy the world, the Gusto decided to join forces with Gem-Knights and Constellars to stop lswarms for good.
Below are the connections that Gustos have, either within their own tribe or with outsiders:
The root of all Gusto decks, this deck focusing on blocking enemy's onslaught using numerous Gusto recruiters while also filling up their Graveyard in order to take advantage of "Caam, Serenity of Gusto", "Contact with Gusto" and "Daigusto Gulldos". Switching monster controls (via "Reeze, Whirlwind of Gusto" and/or "Creature Swap") is a common tactic in this deck, since most Gusto monsters have below-average ATK, and many of them have effects that Special Summon another when destroyed in battle. "Daigusto Sphreez" is the ace of this deck, and when combined with low-ATK trait of most Gusto monsters, can inflict massive damage to opponent (sometimes even leading into OTK).
This build combines Gusto monsters along with some staple DARK monsters to Summon "Dark Simorgh". While Gusto recruiters load WIND monsters in the Graveyard, cards like "D.D. Crow", "Tragoedia", and "Destiny HERO - Malicious" can help set up Synchro Summoning and load the Graveyard with DARK monsters for Dark Simorgh's Summoning.
Basically, it is an Anti-Meta Deck that has similar concepts as T.G. Anti-Meta Deck, but utilizing Gusto monsters instead. Gusto monsters maintain primary defense, while also using beatdown monsters such as "Beast King Barbaros", "Thunder King Rai-Oh", and/or "Malefic Cyber End Dragon", combined with "Skill Drain" and "Shrine of Mist Valley" for putting your opponent's strategy under pressure and at the same time covering virtually any weaknesses in your Gusto defense. "Caam, Serenity of Gusto" ensures that your defense line will always live, even under Skill Drain's and Necrovalley's influences (due to Caam's shuffling-to-Deck effect is a Cost which unaffected by those cards, except you will not get the draw effect in the former's case). Despite its Stun-esque strategy, "King Tiger Wanghu" is not recommended for use, since its effect will automatically destroy any Summoned Gusto recruiters, rendering this Deck's main strategy pointless (unless "Skill Drain" or "By Order of the Emperor" is active).
Another Gusto hybrid Decks which utilizes the 'floating' aspect of Pure Gusto build, combined with destructive ability of "Scrap Dragon" or "Diamond Dire Wolf" for constantly gaining advantage by destroying cards and gaining additional monsters at the same time. "Scrap Beast" is the main Tuner in this Deck, and it can combined with the obvious "Scrap Chimera" or "Summoner Monk" for bringing out "Scrap Dragon" easily.
However, this deck also not without its downsides, though. Since most of the major plays come from "Gusto Griffin", this deck will mostly remain passive until you can draw "Gusto Griffin" and find a way to discard it (similar weakness to Dark World decks). To avoid this, it is recommended to quickly Summon "Dragunity Knight - Gae Dearg" and protect it, since it is the only currently reliable way to search and trigger your "Gusto Griffin".
Finally, having too many "Gusto" recruiters in your hand (at least three or more, or two with the same name) also can reduce their effectiveness, since they can only search for one another from the Deck.
This is probably referencing to the partnership between "Mist Valley" and "Dragunity" during the first generation wars of Duel Terminal world.
All Gusto non-Synchro Psychic-Type monster seems to be having a pairing system between its male and female members, which determined by their Levels. They also have exactly 6 members, which is most likely made of 3 pairs. If sorted from the highest to the lowest, it may resemble a family tree of some sort. According to that, one can be assume that "Windaar, Sage of Gusto" is their leader.
If you look closely to Gusto Psychic-type monsters' eyes (best examples are "Winda, Priestess of Gusto" and "Reeze, Whirlwind of Gusto"), you can see that they have cross-like marking in their pupils (slightly resembling Uchiha Itachi's Mangekyou Sharingan from Naruto series). However, some of Gusto monsters like "Kamui, Hope of Gusto" doesn't share this characteristic and it is currently unknown if the other Gusto members actually share this characteristic as well.
All Daigusto Synchro Monsters and Gusto's non-Psychic-type, non-Xyz monsters share this characteristic.
