Pokémon has a TCG that I am super invested in. I’ve been playing since the launch of the Scarlet and Violet set (March 2023) and I have traveled to different tournaments around Europe (sadly, no good results yet). Here I will present to you some resources that I use for keeping myself up to date and some testing tools.
Formats
Standard
Regular format, conforms 3 years of cards and the rotation of the cards are usually done during the date of the EUIC (march/april of every year). Rotation of cards are done via the regulation mark of the card.
GLC
Format invented by TrickyGym, the format simulates as if you where a gym leader, so you can only use 1 copy of each card (except basic energies) and no rule box cards.
Decks
International/Regional/Special Championship Events
LimitlessTCG is the best website for that. Right there, you can search for tournaments either sanctioned by TPCi (Europe, America and Oceania), TPC (Asia), Japanese Local Tournaments (City Leagues) or online tournaments held by their own platform (using Pokémon TCG Live).
You can also search for the decks that are used, see stats about staple cards for each archetype and several lists from the tournaments.
User created decks
For Standard decks, PokemonCard.io is the best site for searching user-created decks. If you want to have a database for your own decks, I really recommend My LimitlessTCG, as it is the best tool, as of now, to visually create your deck, with statistics and some other tools connected with LimitlessTCG.
For GLC decks, CardBoardWarriors.net is the best site for sharing decks, but I also recommend My LimitlessTCG, as it has a functionality to search for GLC legal cards.
Set info
JustInBasil
JustInBasil is the best website to search for new and old cards, some staples list for each set and see spoilers and proxies of new cards that are going to be launched in the next few months.
Testing
Pokémon TCG Live
The official application for playing is the Pokémon TCG Live. It is a little bit buggy application that works for most of the cases. This is where you can exchange your QR codes from boosters to new cards.
PTCGSim
PTCGSim is a semi-automated tool for playing alone, with a friend or versus yourself for testing. It is a rather simplistic website but full of functionalities. Before using it, I recommend watching the tutorial, to get a full image of what it can do.
Tools for Official Sanctioned Tournaments
Play! Pokémon
Play! Pokémon is the official name for the competitions that Pokémon TCG, as a game, holds. It includes local and regional tournaments. In order to participate in events, you will need to register inside the Pokémon page and create a Play! Pokémon ID.
RK9
RK9 is the official website that allows players for registering for International/Regional/Special Championship
Events. Right there, you will need to fill the Play! Pokémon ID and then you will be able to register for events. Also, as all events, you will also need to register your deck.
Pokedata
Pokedata is a website full of tools but, the most usefull ones are the standings page, where you can see the most up to date information for each big tournament that happens. Information is not official but, you know, it is pretty well calculated.
Pokestats
Pokestats is a rather controversial tool, as it has the same data that Pokedata has, but in a more beautiful and useful frontend. You can follow some people, so you can have, at first glance, the record of your friends or famous people. Also, you can see the decks used by the players, so you can have a record of what you have played against.
CounterPlay
CounterPlay is a tool for having a record of your matchups, with an automatic calculation of the win percentage versus different archetypes.
