This is my take at a "Gogogo" deck. "Gogogos" as a deck strategy are somewhat rare nowadays, since they are simply included into "Onomato" decks in small numbers most of the time. To make the deck running more efficiently, I added quite a few other archetypes to the mix, making this more of a "Gogogo and Friends" list. The "Gogogos" aim, just like the rest of the "Onomato"-related archetypes, to bring out Xyz monsters and work with their effects and often use the "Utopia" cards as their boss monster or game ending options.
In terms of classic "Gogogo" cards, I run one "Gogogo Goram" (solid beater and a slow "Foolish Burial" in monster form), one "Gogogo Giant" (revives "Gogogo" monsters upon being Normal Summoned), one "Gogogo Gigas" (self-reviving monster options which does cost your Battle Phase and is therefore most useful going first), two "Gogogo Aristera & Dexia" (defensive option with an effect that can potentially take care of big beaters on the opposing board) and one copy of "Gogogo Golem - Golden Form" (potentially sizeable stat block with in-built monster effect negation). There are also quite a few "Onomato" cards in the deck which are very helpful in terms of consistency and monster swarming. Those options are two "Dodododwarf Gogogoglove", two "Utopic Onomatopoeia" and one "Zubababancho Gagagacoat", which all have various effects allowing Special summoning from the hand or reviving either themselves or other monsters from the graveyard and therefore fetch a lot of usable monsters for Xyz summons. The three copies of "Onomatopaira" not only help setting up the graveyard but also fetch the right combination of cards, while I also added one copy of "Reinforcement of the Army" for the sole reason of searching for either "Utopic Onomatopoeia" or "Zubababancho Gagagacoat".
Other archetype that are part of the deck include a small "Koa'ki Meiru" engine, with mainly "Koa'ki Meiru Supplier" as a solid Special summon since it triggers upon losing any Rock monster, while one copy of "Koa'ki Meiru Overload", "Koa'ki Meiru Guardian" and "Koa'ki Meiru Wall" serve as disruption and can be easily summoned with "Ties of the Brethren". The added "Diamond Core of Koa'ki Meiru" can give destruction protection to your "Koa'ki Meiru" monsters, but they are mostly there to fetch copies of "Koa'ki Meiru Supplier" for the summon effect (which in turn also searches "Koa'ki Meiru" monsters). Aside from that I decided to run a small and inexpensive "Adamancipator" engine, with two copies each of "Adamancipator Analyzer", "Adamancipator Seeker" and "Adamancipator Signs", which further help accrue Xyz-able monsters onto the field.
The rest of the Main Deck really only features more support cards to make the deck run a little smoother. One copy of both "Barrier Statue of the Drought" and "Fossil Dyna Pachycephalo" are good targets to summon via "Ties of the Brethren" when going first and are also solid options to search and go into via your Normal Summon, since there are situation in which the Special summon block will hurt the opponent more than you. "Doki Doki" is there as setup and as a play-enabler, "Block Golem" is more of a niche option, but will transfer itself into exactly enough materials to start a Xyz summon and "Sentry Soldier of Stone" can revive itself with relative ease, but can only be used for Link summons due to its level. One copy of both "Raigeki" and "Harpie's Feather Duster" seemed pretty much mandatory to me in the deck and are options you can play if the removal cards in the Extra Deck cannot be used. "Foolish Burial" is more graveyard setup while "Monster Reborn" is the obvious choice in terms of monster revival.
The Extra Deck features a number of options to work with and is the main focus of the deck. "Tornado Dragon" is solid backrow removal, "Castel the Skyblaster Musketeer" is non-destruction removal, "Diagusto Emeral" is a card draw option and "Gagaga Cowboy" can be used to inflict the last tick of damage. The aforementioned "Utopia" engine comes in form of two copies of "Number 39: Utopia", which can be used to summon either "Number S39: Utopia the Lightning" (for a 5000 ATK beater against monsters) or "Number 39: Utopia Double" (for a 10000 ATK beater with the single copy of "Double or Nothing!" in the main deck, but which I only included once due to consistency reasons for the rest of the deck). So far, there is nothing out of the ordinary and most players probably already knew of those cards prior to reading this section. "Number 55: Gogogo Goliath" might be less familiar and can serve as a DEF booster and recurrence tool, but mostly finds a way onto the board because it is a "Gogogo" monster and therefore triggers certain cards; "Gagagaga Magician" serves a similar purpose, but can revive previously used "Utopia" monsters for overlays and as 2500 ATK beaters. "Gallant Granite" is the Rock type searcher and therefore a very important tool of the deck. Lastly, the Link monsters in form of "Aussa the Earth Charmer, Immovable" and "Missus Radiant" both help getting cards upon being destroyed and both have solid effects that might come in handy during your turn ("Aussa the Earth Charmer, Immovable" being less useful with her revive effect, but "Missus Radiant" is a very solid tool since it provides solid stat boosts to pretty much everything on your side of the field).
The "Gogogos" as a deck on their own really aged rather poorly, which is why I had to include so many other options. Nonetheless, if you want to play a deck that is capable of spamming Xyz monsters in a more Casual environment, I urge you to give the rocky monsters a go. Furthermore, if you want more information about the "Gogogos" and cards I did not feature in this deck list (or other archetypes for that matter), feel free to visit my blog under this link: https://cubiccreativity.wordpress.com/2020/02/16/archetype-analysis-gogogo/
