JIBX #13 - Eternal Format (Base Set Onward)
Organized by JustInBasil TCG
Custom format

Have you ever wondered what it could be like if Pokémon had a Base Set-on format, with a ban list? Wonder no longer! The Eternal format aims to be exactly that—a pseudo-Unlimited format, but without all of the complete brokenness of the official Unlimited format.

Because of the limitations of PTCGO, all games in the Eternal format will be played using Untap.in.

The entry code required for registration is "eternal".

Format Description

In the Eternal format, all cards released from the original Base Set through the most recently released, tournament legal set are legal, excepting those which appear on the list of banned cards below.

Entry is free for all participants. You must be on the JustInBasil Discord Server in order to participate as this makes communication between participants and the tournament organizer simpler. You can join the JustInBasil Discord Server here.

Prizing for the tournament will be dependent on participation, with first place earning a code per participant at the end of round one and second place earning a code for every two participants at the end of round one.

Notice: Players who fail to be present on the Discord server during the course of the tournament will be ineligible to receive any prizing they might have otherwise won.


The structure of phase 1 will be Swiss, with 30-minute best-of-1 rounds. The number of Swiss rounds will be determined by the official Pokémon Tournament Handbook's guidelines. There must be 9 or more participants for a top cut. Top cut, if there is one, consist of 50-minute best-of-3 rounds. The tournament will have open deck lists, with deck lists becoming visible to other players at the start of round 1.

Always be respectful when conversing with tournament staff, other tournament participants, and other non-participating members of the JustInBasil Discord server. Failure to maintain proper sportsmanlike behavior will result in disqualification.

Also, because of the nature of these alternate formats, it is possible that you or your opponent may accidentally include illegal cards in your deck. Please review the Illegal Deck Process article on justinbasil.com to familiarize yourself with what to do in such a situation.
