OM Mashups Index​

Welcome to Other Metagame Mashups, where we combine the rulesets of various Other Metagames to create new ways to play! Check out the rest of our subforum for general discussion, hub threads, and the occasional event.

Other Metagame Mashups (OMMs) are independent formats, governed separately from their base Other Metagames (OMs). While they often share rulesets with the parent OM, tiering decisions are made for the needs of the mashup. Because of our smaller playerbase and larger number of formats, the majority of tiering changes are done via quickbans based on community input.

This is a subforum of Other Metagames, and all Other Metagames rules are still in effect. In particular, please refer to the Other Metagames Tiering Guidelines while making tiering decisions. Consistency is important, especially when dealing with many smaller formats. Deviation from these guidelines is discouraged but acceptable in certain circumstances.

Tiering decisions are handled by the Council running each format. Council members are selected from passionate members of the community who rise to the occasion. Councils are led by a Tier Leader, elected amongst themselves, who is responsible for:

• Ownership of the hub, and keeping it up to date
• Communication with OM Mashups leadership, including all tiering changes
• Driving internal council activity (voting slates, resource generation, etc.)
• Reaching out for help when necessary

Everyone on the Council is responsible for their respective formats, with duties including but not limited to:

• Listening to the community and responding to their needs
• Voting on bans, unbans, and restrictions and providing detailed justifications for them
• Making update posts in the thread
• Quarterly generation of resources, including at minimum sample teams and a rough VR

If you’re interested in starting a format, here’s what to do:
1) Reach out for help! We’re all in this together, and you’ll always find someone who wants to play with you and form a council. A minimum of 3 players are required to form a council; a 5 player council is recommended.
2) Create a first draft for a hub. This will act as a reference point when people need to check out the metagame. You’ll need to write a brief explanation of the format, and include:

• A full ruleset (Clauses, Bans, and Mechanical Interactions)
• 2-3 sample sets with a brief strategy attached
• Tournament and Challenge Code
• Please ask OM Mashups staff for assistance and clarification with any of these!

3) Submit the draft to OM Mashups leadership, who will provide feedback and edits. Once this process is complete, your metagame is approved and ready to be played!
4) Post it! OM Mashups staff will add the tournament code to our bot Iolanthe, allowing us to set tournaments in the PS! Room.

OM Mashups leadership reserves the right to edit resources, dispute tiering decisions, and promote/demote Council members.

Other Metagame Mashups Tiering Policy and Guidelines

1. Mashup-Specific Tiering Policy:

• Other Metagame Mashups are formats derived from combinations of and modifications to Other Metagames.
  • Mashup Councils should strive to follow the OM Tiering Guidelines whenever possible. These are a clear set of rules that dictate how Councils should approach problematic elements in the metagame.​
  • In exceptional cases, OM Tiering Guidelines can be sidestepped with Project Leader approval. An example of this would be PokeBH's complex ban of Regenerator and Fur Coat/Ice Scales on the same Pokemon.​
• Mashups are separate formats from the Other Metagames they are based on.
  • Tiering decisions made in the base formats do not affect Mashups of those formats.​
  • Sometimes, Pokemon/Moves/Abilities that are banned in the base format are not broken in the derivative Mashup. These elements should be unbanned.
    • Example: Azumarill is banned in STABmons but legal in STAAABmons, where it loses access to both Huge Power and Jet Punch.​
• Mashups are derived from Other Metagames and thus share their mechanics.
  • The mechanics of Mashups do not deviate from the mechanics established in their base formats.​
  • Example: Pokebilities bans Pokemon with broken base abilities, instead of disabling specific broken abilities. Pokebilities AAA and Pokebilities BH abide by this policy as well.​
• Mashups follow the Standard Other Metagames ruleset: Species Clause, OHKO Clause, Evasion Moves Clause, and Overflow Stat Mod.
  • Exceptions can be made in cases like Anything Goes and Doubles formats, up to the discretion of Mashups Staff.​
  • Nearly every Mashup enforces Sleep Moves Clause and Terastal Clause. This is not a rule, but a frequent consequence of the higher power levels found across most Mashups.​

2. Types of Tiering Actions:

• Quickbans are reserved for removing metagame elements that are unquestionably broken.
  • Most of the tiering done by small or new Mashups in their early days is done via quickban.​
  • In larger and more established Mashups, quickbans should be used sparingly.​
  • Quickbans should not be used to remove something that is controversial. Councils should only quickban an element after a unanimous vote.​
• Suspect Tests should be used to balance Mashups featured on the OM Mashup of the Month ladder and with permanent Showdown ladders.
  • Suspect tests last for at least two weekends (9-10 days).​
  • Information and resources on running suspect tests is available in the Other Metagames Tiering Policy thread and section 3 of this guide.​
  • To start this process, create a suspect thread in accordance with the OM Tiering Policy guidelines and submit a draft to the OM Mashups Submissions section subforums. Upon approval, this will be moved to the main subforum to host discussion.​
• Suspect Tournaments are used to hold community votes in the absence of a ladder. These are used sparingly and are difficult to administrate. Consider other options before resorting to these.
  • Suspect tournaments will be held regularly over at least two weekends. Communicate with Mashups staff to create a schedule so players with different availabilities can participate in the process.​
  • Suspect Tournaments are played as Best of 3 room tournaments in the OM Mashups Subroom.​
  • To start this process, create a suspect thread in accordance with the OM Tiering Policy guidelines and submit a draft to the OM Mashups Submissions section subforums. Upon approval, this will be moved to the main subforum to host discussion.​

3. The OMMOTM Spotlight Ladder Process:

• Preparation:
  • Towards the end of the OM Mashup of the Month voting process, staff will give a heads up to formats that are likely to win the vote. The councils should take a few actions, including:
    • Complete any urgent tiering actions. These are usually things like elements missing from the banlist or recent metagame developments. These things are much harder to change once the format is challengeable on Showdown.​
    • Compile at least 3 sample teams and showcase them in the thread/hub. As many as possible are encouraged!​
    • Do your best to create a Viability Rankings. A preliminary viability ranking of High Viability/Viable is acceptable. This is less important than the other steps.​
    • Compile a ruleset that will be submitted to the Showdown team.
      • To do this, we’re going to separate each item into distinct categories.
        • Bans and Restrictions are different, and will be sorted into different lists.​
        • Example: the compiled STAAABmons ruleset from its spotlight in April 2026.​

• Double check your work. You need to reference the hub and the tournament code several times with several people. The hub, tournament code, and submitted ruleset need to match. This is much harder to fix once it’s live on the servers.​
• After completing the previously mentioned steps, reach out to the Project Leaders to proceed.​
  • Most of the time, the Project Leaders will need clarification on aspects of your submission to make sure everyone is on the same page.​
• During the first week:​
  • Keep an eye on the ladder and forum/discussion. The exposure from the spotlight will inevitably find something broken that our smaller community had not thought of yet.​
  • Prepare a tiering action slate by the end of the first week. Some things are going to be obviously broken and will be quickbanned to make the format more enjoyable.​
  • If a suspect is deemed necessary, a proposal must be submitted to OM Mashups leadership and the OM Submissions part of the OM forum as soon as possible.​
    • Suspects take time to get approved and implemented.​
    • The ladder is significantly more active at the start of the month, which increases the accessibility of obtaining reqs.​
    • A guide for making a suspect test thread can be found in the Other Metagames Tiering Policy and Guidelines thread.​
• During the second week:​
  • Set up a poll using Google Forms! It’s important to judge how the metagame is going and how the players are enjoying it.​
    • Important topics to ask about:​
      • Metagame enjoyment, on a 1-5 scale.​
      • Metagame competitiveness, on a 1-5 scale.​
      • Should tiering action be taken on [topic], on a 1-3 scale. 1 is for “no action necessary”, 2 is for “I would not mind if action was taken”, 3 is “action should be taken immediately”​
    • Polls last around 1 week.​
    • Reach out to Mashups Staff if you are having difficulty making a poll.​
    • Update the viability rankings​
• As the spotlight comes to a close:​
  • Take action based on metagame developments and the result of the poll, if necessary.​
  • Consider running a second poll. The metagame will still be developing until the end of the spotlight.​

Questions & Answers:

This thread should be used for simple questions that need relatively simple answers, those kinds of questions rarely lead to meaningful conversation. If you were considering posting in a thread to ask "How can I make this challenge code?" or making a new thread to ask "Where can I play OMMs?" I'd recommend asking those questions here instead. For simple questions related to Smogon ask here. For in-game help/info check the Orange Islands subforum. This section is for competitive discussion only.

When posting in this thread, please follow these guidelines:

• Make sure your question is relevant to OM Mashups.
• Use the search feature to check if the question has been answered before.
• Quote the question you are answering to help keep things organized.
• Do not answer a question if you are unsure.
• Your answers should contain at least a brief explanation, even if it was the simplest of questions.
