Hey /vp/! Here's a faggotorious idea for you. With the inevitable Gen 4 remakes, Fog will return as a weather effect. So, why not flesh it out and make it usuable?

Here are some ideas for fog:
>Base Accuracy for all moves decreased by 12.5%; All Ghost and Dark type moves are unaffected by accuracy drop
>Sound moves fail when used in fog
>Weather Ball doubles power; not sure about type change
>Synthesis, Moonlight, and Morning Sun only recover 1/4 max HP
>Light-based attacks (Solar Beam, Dazzling Gleam, Moonblast, etc.) do half damage
>Effects can be disabled by Cloud Nine and Air Lock
>Can be combined with rain, hail, and sandstorm; sun cannot be summoned under fog
>Fog can be lifted by Defog, Tailwind, Gust, Hurricane, Blizzard, Twister, Whirlwind, among other moves; these moves also ignore the accuracy drop
>New move summons the fog for five turns

What do you guys think? Any other ideas?
