Introducing Custom Formats on TCG ONE!

  • Custom Formats (Beta): TCG ONE now lets you build your own Pokémon TCG format variants! Pick a base format, customize the card pool, deck-building rules, validation filters, and game settings, then publish it for others to browse, deckbuild for, and play. Try it at Custom Formats - TCG ONE. Some options are subscriber-only, and the feature is still a beta mode, so feedback on the forum is very welcome.
  • Environment Effects (Beta): Custom Formats also feature a new Environment Effects which modify some core game rules for extracting a never-seen-before special fun from Pokemon TCG with fully automated game mechanics. (Note that not all Environment Effects are fully tested yet).
  • Custom Format Toolkit: Added the full custom format flow: discovery/detail pages, create/edit wizard, draft creation for owners, clone/publish/archive actions, top decks, pool preview/testing tools, custom-format-aware deck editing, unified format selection in game creation, and support for custom game settings and environment effects.
  • Custom Format Following & Sponsoring: You can now follow custom formats for notifications, and sponsoring is available with Patreon-based slot limits. Sponsored formats are announced and displayed on the home page.
  • TCG1 Midsummer Rewards Festival: To thank our players and to compensate for the Quest Rewards issue, everyone who completed a quest between April 1 and July 31, 2026 receives 3 promo cards and 3 booster packs for free. Rewards are granted automatically on visiting career page. Complete any Career quest during the eligibility period to qualify.
  • May 2026 Ranked Compensation: Added compensation for the faulty Career ranked ladder rewards in May, granting 200 extra coins for each ladder participant (stacks for each ladder).
  • Play, Profile, and Career Polish: Added Play Now buttons on format and deck pages, a new /profile page, a full-page History tab in Career, cleaner transaction history, and a refreshed home page layout.

Bug Fixes:

  • Ranked season rewards were fixed.
  • Set completion achievements now count BASIC (free) cards correctly.
  • The card fan no longer crowds the navbar on desktop or overlaps buttons on mobile.
  • Card search URLs now canonicalize cleanly without creating duplicate history entries.
  • Scan links now redirect to tcg.one with better caching.
  • Deck paginations were streamlined; both My Decks and Deck Garage now use the same pagination component on both top and bottom of the page.

Next Up:

  • Weekly events
  • Metadata and boilerplate for 2022-2026 sets

However, having one small problem…

If I try to include a card and then I search for it, such as this example where I search for “Bulbasaur,” I’m limited to like 6 or 7 cards that match that name, even if I try scrolling through them. (Also, the search results box is really narrow, cutting off some important info like set.) Is there a way to narrow these down with further format info?

Hey crait, long time no talk, I knew you’d come to build your Legacy format. Thanks for pointing out the rough edges, they need some love :slight_smile: I just pushed an update to fix the search limit issue, will be live in ~5 mins.

Thanks for the hotpatch!

If I can get the 20 or so example decks I made online and the custom format tested, I’m willing to host a tournament in some way with a small prize. :slight_smile:

Hi @Admin, could you please fix the Gen 2 (Base-Neo, Rocket-On, Neo-Skyridge, E-Card) self damage while having Metal energy Attached interaction? If you’re Steel type and confused, and fail the coin flip, and have Metal attached, it should be -10. If you’re NOT Steel type, and have Metal attached and are confused and fail the coin flip, you don’t do any damage to yourself with the attack failing. Its always been this way on here and now suddenly for the past few months it changed on here and youre dealing 20 damage to yourself regardless of Metal. The ‘placing damage counters’ when Confused and attack failing didn’t start until later eras.

Awesome! Thanks for your help!

I got the format made on the site and 35 starter decks made, too. :grinning_face:
