My apologies if this doesn't go here.
This board doesn't have a thread for this game, even though we know a lot of people here play either master duel, the tag force/world championship games or in real life. Here's some links anyway, the game is actually pretty easy to understand.
>Master Duel
<https://store.steampowered.com/app/1449850/YuGiOh_Master_Duel
This is the official simulator, made by KONMAI itself. Very F2P friendly if you want to build a certain deck (or just buy 3 structures, also very cheap, with dragonmaid and zombie being the best ones), and recent changes have made the experience "on-rails", so just download it and give it a go.
Your first purchases should be the staples: Ash Blossom & Joyous Spring, Maxx C, Infinite Impermanence, Called by the Grave and Crossout Designator. These go in every deck, and you need 3 of each besides Called by the Grave (2) and Crossout Designator (1)
>EDO Pro
<https://projectignis.github.io/download.html
The best unofficial simulator bar none, really fast with updates, runs on potato computers/phones and you can customize just about everything for free. Not a lot of people playing online though, but at least it's chinese-free.
Doesn't have a story/solo mode, so you just build your deck and take it online, still useful if you want to learn the ropes.
>YGO Omega
<https://omega.duelistsunite.org/
Botnet, bitcoin miner and takes a lot of resources, it's still an alternative as it has a lot more people playing online, however the program is notorious for using a lot of resources and the devs outright telling people to fuck off when asking if the code will ever be made public, so everyone takes it as the game mining bitcoin for them. It also needs a discord account to play online in the first place.
So why even bring it up, you say? Because the UI is less of a clusterfuck than EDO, and it's less autistic if you want to play against bots, as Omega lets you duel them regardless of how many illegal cards they run, so it's a decent choice if you want to test out a certain deck before you take it online in EDO or irl before you spend all your savings on shiny cardboard only to lose to a a fellow autist who spent more on even shinier cardboard.

The only decent wiki, and the devs are still a bunch of tranny lovers, they infamously removed the "list of female monsters" after a tranny made a video about it, stating how transphobic
LOL and irrelevant it was, even though there's a reason for its existence (in the anime ZEXAL there's a card, Zombiestein, that won't attack female monsters, and over time people just kept adding to that list).

Go here to get an idea of what your deck should include, i'm not saying just copy paste someone else's build and use it, but checking out someone else's deck can give you ideas on what to run, as you probably don't remember what every single card does (there's around 30k now) and how they could benefit your deck.

If you ever need a card, check prices here first, as local game shops will rob you blind. If you can't buy it here because it's out of stock, your only other real choice is ebay.
>Overall tips for TCG/OCG
Use sleeves, dragon shield if you don't mind the price and ultrapro if you do, both are really good.
Konami sleeves are trash, however they're really pretty, so only buy them if you're planning on maxing out the rarity of your cards and double sleeving them.
Double sleeving is unnecessary, and even in local tournaments people will ruleshark you about it, which can lead to a DQ. So just double sleeve your favorite decks and only use them in locals against friendlies.
Don't go crazy on a deck box, as long as it can hold your deck (40 to 60 main deck cards, 15 extra deck cards and 15 side deck cards), field center and a single dice it's more than enough.
Unlike master duel, you don't need to buy ALL the staples, only buy what you need, unless you fancy wasting all your money on cardboard, believe it or not this game is addicting.
Don't be afraid of playing online/irl against randoms, the game is played mainly by autists. Just steer clear of metafags and trannies.
