Not gonna lie here, it's getting less and less fun to do this. Needs something... 'different' to spice it up a bit.
Regardless of my complaining, I'll just get this done and over with for the next 2 weeks. Descriptions may not be fully done.
Pokemon: Feraligatr
Type: Water / Fighting
Ability: Torrent / Adaptability / Sheer Force (HA)
Old Stats: 85 / 105 / 100 / 79 / 83 / 78 (530 BST)
New Stats: 95 (+10) / 125 (+20) / 100 / 89 (+10) / 53 (-30) / 108 (+30) (570 BST)
Added Moves: Vacuum Wave, Pursuit, Calm Mind
Niche: A Dragon Dancer capable of going mixed, carrying priority on both sides of the spectrum, with a strong offensive typing and two fantastic offensive abilities to match. Feraligatr's main strength comes from access to said Dragon Dance and Sheer Force, granting a massive power increase to his primary STAB move Liquidation, as well as his coverage moves Crunch and Ice Punch. On Mixed sets, Scald, Ice Beam, and Focus Blast get this generosity. He's also capable of Pursuit trapping Pokemon that may fear Feraligatr's raw strength, such as Ghosts. Calm Mind is a niche option on a set to improve his shoddy Special bulk and increase his Special Attack back into strong territory. Speaking of that Special Defense, that's Feraligatr's main weakness - while the rest of his stats are compensated for it, his Special Defense is significantly lacking, meaning any Psychic type or special Flying or Electric type that decides to even glance at him funny will likely knock him senseless. Avoiding these Pokemon and chipping away at the opposing team's walls will keep Feraligatr kicking and healthy.
edit: as im typing this up samtendo has his feraligatr, nuuuu
Pokemon: Garbodor
Type: Poison / Fighting
Ability: Skill Link / Poison Touch / Filter (HA)
Old Stats: 80 / 95 / 82 / 60 / 82 / 75 (474 BST)
New Stats: 95 (+15) / 125 (+30) / 102 (+20) / 60 / 92 (+10) / 95 (+20) (569 BST)
Added Moves: Defog, Icicle Spear, Thunder Wave
Niche: An odd mix of strength, firepower, and utility makes Garbodor a swiss-army-knife of Pokemon, capable of fufilling many different roles that you may desire out of it, but maybe not to the level of other mons. On the Support side of things, Garbodor's natural bulk and decent speed of 95 hits a tier where he can outspeed most common fatmons and start setting up layers of Spikes, regular or poison, Thunder Wave, Toxic, or Defog hazards away. However, offensively, Garbodor can run Poison Touch to gimmick out Poisons onto opposing Pokemon through Drain Punch sets, or run Skill Link with Icicle Spear, Rock Blast, and Bullet Seed to have free 125 base power coverage moves. However, Cloyster can do the Skill Link job better, with STAB Icicle Spear and Shell Smash, while a myraid of supporting pokemon have the ability to do what Garbodor can to support. However, Garbodor also has access to immunity to Toxic while also threatening out Steels via the possibility of Swords Dance Drain Punch, so teams must always be wary.
Pokemon: Tapu Bulu
Type: Fairy / Fighting
Ability: Grassy Terrain / Poison Heal (HA)
Old Stats: 70 / 130 / 115 / 85 / 95 / 75 (570 BST)
New Stats: 70 / 130 / 95 (-20) / 75 (-10) / 85 (-10) / 115 (+40) (570 BST)
Added Moves: Drain Punch, Play Rough, Autotomize
Niche: Tapu Bulu gains access to STAB Play Rough, automatically making up for the fact he can't use Grassy Terrain as well anymore. Bulk Up sets now can appreciate Drain Punch as a reliable STAB option and Poison Heal, making Bulu incredibly hard to take out after a boost or two. A swapped around stat spread also makes better use of these options, with Bulu being significantly faster at the cost of some bulk (able to be made up for with PHeal and access to Play Rough.) On the offensive spectrum, Superpower and Play Rough form great coverage, with Stone Edge hitting Flying types that may otherwise resist Drain Punch and not care for Play Rough. Autotomize can set up for danger very quickly late-game with Bulu steamrolling out of control, and Double Dance sets are even scarier. A lack of way to improve its Special bulk barring an Assault Vest hurts, however, same with a weakness to Sludge Bomb/Wave and Iron Head.
