The Gusto archetype is an interesting one focused on the pretty niche combination of WIND Psychic monsters, and the not remotely niche combination of WIND Winged-Beast monsters. Like Winda up there, many of them have effects that let you summon a new monster when they're destroyed by battle. This allows you to make chains of Winda into Gulldo into Egul into Winda, and so on. Egul can also search Gusto Thunbolt, which in turn can search any other Psychic Gusto monster in our deck. Cool! The sheer number of Tuners in this list, and how this chain involves at least two Tuners, makes Red Nova Dragon both accessible and very strong. But where does the DARK part come in? See, there are enough dark staples like Sangan and Gorz that are useful in any deck, that I decided to include them here to enable one of the strongest "what-if" monsters in the 5D's era, Dark Simorgh. Our dark count is relatively low, with only 8 in total in the main deck, but it's enough to make Dark Simorgh a very powerful threat. Special summoning it from the hand or graveyard by banishing a dark and a wind from the opposite location makes it easy to catch the opponent off guard with it, and preventing them from setting cards, which includes both face-down defense position monsters, and spells and traps, is deadly in this era. Additionally, cards like Creature Swap and Reeze, Whirlwind of Gusto make it very easy to steal your opponent's strongest monster in exchange for one of your weaker ones! Just remember that Winda has to be destroyed by your opponent's monster specifically, so Creature Swap doesn't work well with it! Before I go into the list, a couple important things to note about Gustos in Over the Nexus specifically; first, Winda is named "Wynnda, Priestess of Gusto", a spelling error likely referring to Winda's canonical sister, Wynn the Wind Charmer. Second, and more important, Reeze is bugged; she lets you select ANY monster to give to your opponent, not just a face-up Gusto monster like the text says. Whether or not you exploit this bug is up to you, but I'd advise against it if you're playing against a human opponent.
