Generation NEXT!
========================================================================

Instructions
------------------------------------------------------------------------

Gen-NEXT hasn't been updated in a very long time, but is still playable by
using the `/challenge gen6nextou` command in a PM chat box.

Manifesto
------------------------------------------------------------------------

The goal of NEXT is to improve the diversity of the OU metagame by only doing
things that could plausibly be done between gens.

Specifically, the core rules of NEXT are:

1. no base stat changes
2. no removing from movepools
3. no removing from ability distribution
4. no typing changes (except on formes)
5. no buffing OU mons, except maybe tiny buffs to mons at the bottom of OU
6. no doing things that make zero sense flavor-wise

What's left is mainly changes to how abilities and moves work, which is
most of what NEXT is about.

A good example is what Game Freak did by giving Ditto the Imposter ability.
This gave a Ditto a role in OU, while still making sense flavor-wise, and
without removing anything it used to have.

A good example of what NEXT changes is Cherrim. We have taken an interesting
idea (ability designed for Sunny Day support) and made it viable in OU.

This approach is in sharp contrast to many mods that do change many things on
NEXT's "don't change" list. The result is a metagame that feels a lot like
a new generation: existing OU threats stay mostly the same, but many new
threats and strategies are introduced.

And yes, we know that "no base stat changes" has been broken in Gen 6. We're
still not doing it, because it's hard to constrain and hard to keep track of.

Changes
------------------------------------------------------------------------

Generation NEXT currently makes the following changes:

Major changes:

- Stealth Rock now does 1/4 damage against Flying-types, and 1/8 damage against
  everything else.

- Drives will change Genesect's typing immediately after switch-in, to Bug/Ice,
  Bug/Fire, Bug/Electric, or Bug/Water. However, Download will not activate for
  Genesect unless it holds a Drive.

- Unown gets an item named Strange Orb (select "Stick" in the teambuilder)
  It doubles its SpA, SpD, and Spe, and changes its type to the type of its
  Hidden Power.

- Weather moves, such as Sunny Day, Rain Dance, Hail, and Sandstorm have +1
  Priority.

- Forecast will make weather moves last forever. Cherrim will make Sunny Day
  last forever. Phione will make Rain Dance last forever. Cryogonal will make
  Hail last forever. Probopass will make Sandstorm last forever.

- Hail is improved:
  - Silver Wind, Ominous Wind, and Avalanche deal 1.5x damage in Hail
  - Snow Cloak no longer modifies evasion, but instead decreases damage by 25%
    in Hail (and 12.5% out of Hail)
  - Ice Body has 30% chance of freezing a contact move (and grants passive
    healing out of Hail, too)
  - Thick Fat, Marvel Scale, and Flame Body grant immunity to Hail damage

- Freezing doesn't have a 20% thaw chance. Instead, thawing happens at the end
  of the second turn. Because this new freeze effect is a nerf, Blizzard now
  has a 30% chance of inflicting freeze.

- Swift Swim, Chlorophyll, and Sand Rush are nerfed to give a 1.5x speed buff instead.

- Every Hidden Ability is released.

- Moves with a charge turn are now a lot more powerful. They remove Protect and
  Substitute before hitting, they always crit (although their base power has
  been adjusted accordingly), they have perfect accuracy, and one other change
  depending on the move:
  - SolarBeam: heal 50% on the charge turn, 80 bp
  - Razor Wind: 100% confusion, 60 bp
  - Skull Bash: +1 Def, +1 SpD, +1 accuracy on the charge turn, 70 bp
  - Sky Attack: 100% -1 Def, 95 bp
  - Freeze Shock: 100% paralysis, 95 bp
  - Ice Burn: 100% burn, 95 bp
  - Bounce: 30% paralysis, 60 bp
  - Fly: 100% -1 Def, 60 bp
  - Dig: 100% -1 Def, 60 bp
  - Dive: 100% -1 Def, 60 bp
  - Shadow Force: 100% Ghost-Curse, 40 bp
  - Sky Drop: 100% -1 Def, 60 bp
  - Phantom Force: 100% -1 Def, 60 bp

- Recharge moves are similarly buffed. They have 100 base power, always crit,
  and they only recharge if they KO. Be careful - in return for a KO, they
  still give the foe a free switch-in _and_ a turn to set up.

- Flower Gift now only boosts Sp. Def, but if Sunny Day is used while Cherrim
  is out, the next switch-in also receives +1 SpD

- All Quiver Dancers (except Smeargle) get an item named Gossamer Wing (Select
  "Stick" in the teambuilder). It makes them take half damage from Rock, Ice,
  and Electric moves if they are Flying type, prevents them from taking
  double SR damage, heals 1/16 after using a Status move, and makes Twister
  do 1.5x Damage.

- Swarm also makes the user take half damage from Rock, Ice, Electric moves,
  and Stealth Rock if they are Flying type.

- Relic Song switches Meloetta's SpA and Atk EVs, boosts, and certain natures,
  specifically: Modest <-> Adamant, Jolly <-> Timid, other natures are left
  untouched. It's now 60 base power +1 priority, with no secondary.

- Shuckle gets Berry Shell (select "Stick" in the teambuilder), which gives a
  50% boost to Defense and Sp. Def.

- Ambipom, Spinda, and Mr. Mime get Sketch as an egg move, allowing it to use
  exactly one move not normally in its learnset.

- Spinda gets V-Create, Superpower, Close Combat, Overheat, Leaf Storm, Draco
  Meteor.

- Echoed Voice now has 80 base power, hits once, and then, 2 turns later,
  hits again for 80 base power. It's like Doom Desire, except it still hits
  that first time.

- Confusion now deals 30 base power damage every attack, but does not stop
  the attack. It now lasts 3-5 turns.

- Parental Bond now deals half damage on both hits, but confers perfect
  accuracy like all multi-hit moves.

- Life Orb now behaves much more consistently as normal recoil. Reckless
  will boost every move if Life Orb is held, and Rock Head will negate Life
  Orb recoil.

- Twister is now a 80 base power Flying move with a 30% confusion chance

- Floette-Eternal-Flower is released.

New mechanic: Signature Pokémon:

- Certain moves have a Signature Pokémon associated with them. A move will
  deal 1.5x its usual damage when used by its Signature Pokémon. Some of these
  moves also receive other changes that apply to all Pokémon using the move -
  those changes are listed in parentheses.

  - Swampert: Mud Shot (60 base power, 100% accuracy)

  - Kyurem: Glaciate (80 base power, 100% accuracy)

  - Octillery: Octazooka (75 base power, 90% accuracy, 100% -1 accuracy)

  - Serperior: Leaf Tornado (75 base power, 90% accuracy, 100% -1 accuracy)

  - Weavile: Ice Shard

  - Sharpedo: Aqua Jet

  - Hitmonchan: Mach Punch

  - Banette: Shadow Sneak

  - Masquerain: Surf (10% -1 Spe)

  - Snorlax: Snore (100 base power)

- Again, note that while the Signature Pokémon will get the 1.5x damage boost,
  all Pokémon will get the other changes to the move listed above.

New mechanic: Intrinsics:

- Big Root: also acts like Leftovers + Shell Bell for Grass types

- Black Sludge: heals 1/8 per turn for pure Poison types

- Focus Band: breaks on first hit, but allows pure Fighting types to survive
  that hit with 1 HP (so basically it'd be a Focus sash that stays intact
  after residual damage); does nothing for other Pokémon

- Wise Glasses: 1.2x Special damage for pure Psychic types

- Muscle Band: 1.2x Physical damage for pure Fighting types
