A couple years ago my friend and I got into playing Yugioh together. I'd played it as a kid, but I pretty much stopped paying attention around 2008 or so. We tried to learn all this new stuff - Synchros, Link Monsters, waifu taxation - but it just didn't feel worth it, since it wasn't the game that either of us remembered nor did it make things any more fun. So, we came up with our own metagame to enable our brand of idiocy. Our ruleset is basically "no cards from after 2008 (except for ones that enable pre-2008 jank), no banned list (but show a little restraint), stupidity only, Final Destination." It really is how Yugioh was meant to be played, I think. One of our favorite things is to challenge each other to make decks with different cards or archetypes, and this list was borne out of one such challenge. We both came up with Mokey-Mokey decks and after a lot of testing eventually settled on something like this as the "ideal Mokey deck" for our purposes.
With all that said, this deck is probably not going to be particularly useful to the average Yugioh player. The abundance of banned cards, all to enable one of the worst possible monsters, ensure that this bew is fit for only the kitcheniest of kitchen tables. Still, for me it's a lot of fun, so I wanted to share it with you. Maybe it will inspire other, better ideas, or else just encourage you to also ignore the banned list. I dunno.
With Mokey-Mokey, the best way to win is no doubt by checking your opponent in to the Smackdown Hotel. If you can get a full board of Mokeks in play, you can potentially wipe them out completely in just one attack step. To enable that kind of scenario, we have a lot of floaters - full playsets of both Shining Angel and Nova Summoner, plus a full suite of Last Will. The floaters let you not only search for your Mokeys, but also weather attacks until you're set up (floater into floater into floater into floater can be a very useful thing). As well, to help you flood the board you've got Ultimate Offering, the League of Uniform Nomenclature, and you can further stall with Cloudians and Sanctuary in the Sky.
For card advantage, we've got Graceful Charity (which both lets you dig and enables graveyard shenanigans), plus a Pot of Greed for good measure. White Elephant's Gift doesn't trigger Mokey Mokey Smackdown, but it can still be nice in a pinch. If you do get into a situation where you need to trigger your own Smackdown (which you will), then Raigeki Break can set off your chain of destruction. Everything else basically just helps you recycle your Mokeys.
Not the most amazing deck in the world, but a good bit of fun. Try it out I guess.
