The metagame should have some sort of punishment for guessing wrongly, as well as an option to completely opt out of guessing to prevent raging over seemingly impossible guesses by the opponent after a series of wrong guesses.
. Hello ANinjaDude 
Holy cow, I found this as "Base Power Damage" in Gen 6: https://www.smogon.com/forums/threads/base-power-damage.3528895/True Strike
Premise of the Metagame: A move's base power is equal to the damage dealt. For example, non-STAB Flamethrower will deal 90 HP.
Some mechanics:
STAB still exists, a STAB Flamethrower will do 135 HP.
Type-effectiveness still exists, a 2x super-effective non-STAB Flamethrower will do 180 HP.
Critical hits still exist, a non-STAB Flamethrower on a critical hit will do 135 HP and will ignore stat boosts.
Stat boosts still exist, a +1 SpA non-STAB Flamethrower will do 135 HP. A +1 SpA non-STAB Flamethrower against a +1 SpD Pokemon will do 90 HP.
In doubles, spread moves still lower damage to 0.75x, weather and terrain effects still take place, burn effects still take place, and any move, ability, or item effects (like Fluffy, Choice Band/Specs, Eviolite, etc.) still take place.
Strength Sap and Confusion damage will still use the actual Attack stat (idk if there is a more elegant way to do this)
Moves with variable base power, like Gyro Ball, Heat Crash, or Eruption, do damage based on their BP.
Anything based on percentage, like secondary effects, Life Orb, Recover, hazards, burn/poison, still work as normal.
(lmk if i missed something btw)
Strategy:
All EVs would go into HP and Spe, with Timid nature for lower Atk. No other stat matters.
Speaking of Eviolite, it's basically 50% more HP so some NFE mons would prefer this over using the evolved Pokemon.
Drifblim is a cool Pokemon, with super high HP and access to Will-O-Wisp and Calm Mind and decent attacking moves like Shadow Ball.
Azumarill has decent HP, but mainly has access to Huge Power alongside boosting with a massive 170 HP Liquidation and can use Belly Drum.
Mixed Pokemon can be run a lot viably, as they are not held back by their weaker attacking stat. This could help beat defensively setting up Pokemon.
Bans:
A lot of Ubers could be freed, but I think Calyrex-Shadow always finds a way to break the tier it is in. Koraidon and Miraidon also look pretty strong and banworthy here. Maybe Zacian/Zacian-Crowned also banworthy?
On the defensive side, definitely the pink blobs are banned, Blissey and Chansey have too much HP with recovery and moves like Calm Mind and even Defense Curl maybe.
On the topic of pink blobs, Alomomola looks like another defensive behemoth and probably banworthy as well.
Eternatus has really good HP and Spe, which is exactly what this tier wants. I think it could possibly be a banworthy jack of all trades with strong STAB moves like Dynamax Cannon, recovery, Toxic. What more could you want?
Arceus could also be problematic similar to Eternatus, but now with a choice of typing, strong STAB move, recovery, and good utility. i guess that answered the question
Questions for y'alls:
Is having only 2 relevant stats gonna lead to the impossibility of a balanced metagame?
Would this metagame be too centralizing?
What other banworthy stuff am I missing?
What other mechanics am I missing?
Would this metagame be fun to play?
I can't submit this
Does the "defending" Pokemon take full damage? If I switch my Forretress-protected Walking Wake into a Flamethrower, does Forretress lose all its HP? Would Sturdy activate? Have I misunderstood how type interactions work?CANNON FODDER CUP
Metagame Premise: Based on your team-preview ordering, your active pokemon will use the preceding pokemon as its "substitute" upon every switch-in. In other words, the first damage you receive after switching in will instead be deducted from the health of the preceding pokemon in team-preview order.
Q & A
Q: What happens if the preceding pokemon faints?
A: Then, you lose access to your substitute, damages work normally.
Q: How does it work for the lead pokemon?
A: 6th pokemon is used as a fodder.
Q: How do status moves or the secondary effects work?
A: These apply to the active pokemon.
Q: How do fodders work?
A: The first damage is received by the fodders with their defensive stats and typing taken into account.
Strategy: This meta would likely center around set-up sweepers paired with bulky pokemon with recovery / regenerator. I also see hazard/status stacking and stall builds being viable options as well. Slow pivots also seem very good.
Bans: Starting with OU Banlist
Questions for the community: Do you think this would be fun to play? Anything broken that sticks out? Any changes to the meta that would make it more playable?
Yes, that is the interaction that I had in mind. I didn't think far into the Sturdy activation (or other abilities).

Status MovesROM actually has a version of this called "Proxy War" which is just mons using substitute without the boost part.inspired by this post
Premise
When a Pokemon switches in, it automatically uses the Move Substitute.
When a Pokemon is behind a substitite, its all base stats except HP are raised by 20.
Bans and Threats
It will be disappointing if people just switch between 2 Regenerators forever. Either banning Regenerator itself or implementing an Ability Clause can solve this problem. As a ban-unhappy player I'm leaning towards Ability Clause.
Broken or not I think it a fun idea to unban Baton Pass for a test :)
Similar to Baton Pass but it has limited Pokemon pool to learn it and you need to wait for the substitute to break to use this Move.
Well.
They really sound scary. I can see Belly Drum and Shell Smash banned at least.
They are both ways to ignore the opposing substitues, making them waste 25% of max HP on switch-in.
It controls setup, it wastes the HP of the Pokemon switched in, and it deals hazard damage.
Hazards is a very important component of the meta since it heavily restricts switch-in. However Knock Off may not be very useful here and thus Heavy Duty Boots can be very popular.
They are mostly useless and Sleep Clause may not be implemented. Use Sing to catch your opponent by surprise.
Question(s)
Q: What should the boost be for Pokemon behind a substitute? Maybe raise Pokemon's stat stages instead?
Last mon Kingambit <50s will have a very respectable 2.25x damage increase.This isn't very likely to go anywhere, I much prefer the idea of Zero Waste since Santa Cup is more luck based whereas Zero Waste is revolved around skill.
Love the idea but OMs sadly don't support natdex. I think it should still have the physical/ Special split so that it still feels right (like, what do you mean I punch someone with a bit of heat and it uses my magic powers?).
Gholdengo - the innate immunity to status moves combined with the good typing and the possibility to get immunities to even more moves might be too much of a threat.
We already got a similar format in here https://www.smogon.com/forums/threads/sharing-is-caring.3727118/
This sound like it just promote fat, either stall or bulky set up too much, which usually doesnt end up being all that fun, specially for the average ladder player, as games would take for too long for a casual format.Vaccimon (Not sure of the name)
Premise
A pokemon develops immunity to moves it got hit by for as long as it stays on the field.
Explanations
If a pokemon would get hit by a move it already got hit by previously (including status moves) that move does nothing.
If a move doesn't hit (because of an accuracy check or any other reason, the pokemon doesn't get immunity to that move)
Moves that target the user are also affected, this means you won't be able to sword dance twice without switching, because of move immunity.
The immunity is based on the move, not the pokemon using the move, this means that if 2 different pokemons use the same move on the same target the immunity still stands.
It could work in singles, but I think it's way more interesting in doubles.
Bans
Possible ban
- Moves that force the target to switch.
- Baton pass
Viability shift
Questions
- Choice items lose a lot of value being unable to hit the same mon twice.
- Buffing moves and healing moves that target yourself can only be used once without switching.
- Defensive mons that can stay on the field for a long time gain a lot of value by amassing immunities to multiple moves.
- Probably a lot more things...
How do multi-hit moves work?
The pokemon won't be immune until the move is done resolving.
What about moves that don't target?
Moves like reflect, light screen, spikes, trick room, rain dance, etc. Are unaffected by the immunity rules.
How does redirecting moves work?
Magic bounce will reflect the status move and give immunity to the pokemon that gets hit, not the magic bounce user.
Follow me can only be used once, because it targets the user, but if a move gets redirected to the user of follow me they will get immune to that move too.
How does transfom work?
The pokemon that gets transformed into can no longer be the target of transform.
Transforming into a pokemon that has move immunities does NOT copy those move immunities.
What about moves like outrage?
You probably don't want to use moves that trap you into using them in this OM. A pokemon hit by outrage becomes immune to outrage.
What if I hit a substitute?
The pokemon won't get the immunity, and the substitute cannot get immunities.
I dont think this would be possible to code, and doesn't sound fair for users with any degree of lag.JOHN MONS
Premise: both players start with a 300 second timer which does not refresh. Every 50 second time interval has passed, ALL of your pokemon's offensive moves deal a cumulative additional 10% more damage. If your timer reaches runs out, you lose the game.
e.g.
start of battle (300-251s timer) : 0% more damage.
250-201s timer: 10% more damage.
200-151s timer: 20% more damage.
150-101s timer: 30% more damage
100-51s timer: 40% more damage.
50-0s timer: 50% more damage.
Banlist: Standard OU clauses and banlist.
Threats and Strategy:
Protect can help you timeout your opponent.
We used to have a format called dual wielding or something like that for multiple items, long story short, there isnt that much item variety in the game for this to be interesting (specially when the better items are way better than everything else, as most are very niche on their use) and is generally not worth giving up on anything for an item.
Doesnt sound too bad, but the excessive min maxing may end up turning this into a very fat format as offensive mons gets very frail so the even the somewhat passive walls can deal a lot of damage (specially when just two stats is enough to max out, as stats cap at 255 which limits this format a lot).
