All-Weathermons (V2)
(Other suggestions for the metaname are welcome)
(First of all, my apologies for my poor English)
Intro: Two weeks ago I did a suggestion for a metagame After some brainstorming with some of you guys, including the idea of removing the RNG in the previously metagame as a key element, I decided to revisit the idea.
Premise: Every match is played with rotating weather, field and dimension ('room') conditions which are predetermined in their sequence and duration.
Explanation:
The weather conditions will rotate in the following order: Sand > Snow > Rain > Sun > Strong Winds.
The terrain conditions will rotate in the following order: Grassy Terrain > Psychic Terrain > Rainbow > Electric Terrain > Misty Terrain > Sea of Fire.
The dimension conditions will rotate in the following order: Wonder Room > Trick Room > Magic Room > Gravity.
Every condition with be active for 3 turns.
The weather conditions will start on turn 0 (and thus rotate at the end of turns 3, 6, 9, ... [0 + 3n]).
The field conditions will start at the end of turn 1 (and thus rotate at the end of turns 4, 7, 10, ... [1 + 3n]).
The dimension conditions will start at the end of turn 2 (and thus rotate at the end of turns 5, 8, 11, ... [2 + 3n]).
This means that on turn 3 the active conditions are Sand, Wonder Room and Grassy Terrain are active, while on turn 11 Sun, Magic Room and Electric Terrain are active.
This way every turn will have a unique combination of conditions that will only start repeating itself after 182 turns.
Example:
As the metaname suggests, this meta largely promotes the use of mons that are able to function well in a lot, if not all, of the field conditions. One could to this by making a balance for each mon on how they function in every field condition:

(+) Strong Winds, Rain
(-) Sand, Sun, Grassy Terrain, Electric Terrain, Psychic Terrain, Misty Terrain, Sea of Fire, Magic Room, Trick Room, Gravity

(+) Sun, Sand, Grassy Terrain, Sea of Fire, Trick Room, Gravity
(-) Rain, Magic Room

(+) Sand, Grassy Terrain, Psychic Terrain, Trick Room, Gravity, Wonder Room
(-) Rain, Misty Terrain, Sea of Fire, Magic Room

(+) Snow, Grassy Terrain, Psychic Terrain, Rainbow, Gravity
(-) Sand, Strong Winds, Sea of Fire, Misty Terrain, Magic Room, Trick Room

(+) Sun, Grassy Terrain, Psychic Terrain, Electric Terrain, Misty Terrain, Rainbow, Sea of Fire, Gravity
(-) Rain, Sand, Magic Room, Trick Room, Wonder Room
It is important to see all three field conditions as separate. For example, Heatran functions well during basically every field condition, so using one will rarely feel like a detriment. When we look at Iron Moth, it looks to be pretty balanced and slightly leans towards having more benefits from the field conditions since it loves six out of six terrain conditions. However, it's very important to note here that Iron Moth hates three out of four dimension conditions. Think makes for a interesting dynamic. Of course there are a lot more mons to explore, but I would love to see you guys come up with ideas for the best all-weathermons.
Questions:
Q1 - A variation to this idea, which I would seriously consider, would be to let all conditions start on turn 0, which means that Sand, Grassy Terrain and Wonder Room would be active from turns 1 to 3, followed by Snow, Psychic Terrain and Trick Room from turns 4 to 6. This does make the rotating conditions easier to manage, but (in my opinion) Which variation do you think is better and why?
Q2 - Ignoring the RNG aspect for a second: what if only the starting conditions were randomized, after which they would follow their pre-set sequence and duration. Do you think this adds to the metagame since it forces timing in making plays, or would you prefer everything to be pre-determined to encourage more pre-game strategizing, and why?
Q3a - Do you think that these pre-set sequences of every condition are logical and don't encourage any overpowered overseen strategies?
Q3b - Do you think that the pre-set duration of 3 turns for every condition are impactful enough while not overstaying their welcome?
Q4 - Primordial Sea, Desolate Land, Swamp and Tailwind (and technically Mud Sport and Water Sport) are the only field conditions that are not included in this metagame. What do you think about that?
Bans:
Pokémon
At this point, I find it too hard to say what mons will be broken.
Abilities
All weather-setting abilities: Drizzle, Drought, Sand Stream, Snow Warning and Deltra Stream
All terrain-setting abilities: Grassy Surge, Electric Surge, Psychic Surge and Misty Surge
(F for no dimension setting abilities lol)
If it is possible to modify these abilities to not affect the permanent field conditions, these bans would not be needed. In addition, a pop-up could be given if a player searches for a match with a team that has a mon with a weather-setting ability (same pop-up when using banned mons/moves).
Moves
All weather-setting moves: Rain Dance, Sunny Day, Sandstorm, Snowscape and Chilly Reception
All terrain-setting moves: Grassy Terrain, Electric Terrain, Psychic Terrain and Misty Terrain
All dimension-setting moves: Trick Room, Wonder Room, Magic Room and Gravity
If it is possible to modify these moves to not affect the permanent field conditions, these bans would not be needed. In addition, a pop-up could be given if a player searches for a match with a team that has a mon with a weather-setting ability (same pop-up when using banned mons/moves).
Steelroller - as it becomes a free 130 BP Steel-type move when any terrain is active.
Ice Spinner - as it clears the field of terrain. This is not needed if the secondary effect of Ice Spinner can be nullified with mods.
Other:
I am unaware whether some of these ideas would be impossible to implement in the simulator, so I would love to hear if there are such limitations.
Final:
As stated in my previous suggestion, I've always found field conditions an insanely unique mechanic added in mons. However, Rain and Sun have been the strongest conditions ever since their introduction. With this metagame, I hope to inspire people to make interesting teams that can function under the more obscure conditions of Magic Room, Wonder Room and Gravity, or even Misty Terrain and Rainbow.
I am once again very curious about your opinions on this OM. I am also very interested in hearing suggestions to improve, or even ideas you came up with to use in this metagame!
