Krookodile: C+ Rank -----> B- / B Rank
Krookodile is a very underrated threat in the current OU metagame, and it is kind of hard to see why. Krookodile has a solid defensive stat spread of 95 / 80 / 70, with a high base 117 Attack stat, and backed by Intimidate, its physical bulk sky rockets. Krookodile's unique typing gives it resistances to Rock-, Ghost-, and Dark-type moves, allowing it to be the perfect counter to Tyranitar, amongst other things. It also gives it an immunity to Electric- and Psychic-types, which can come in handy. The best drawing point of Krookodile is its STAB Knock Off and STAB Earthquake, both greatly spammable moves, being only resisted by Mandibuzz, Heracross, Chesnaught, Hydreigon, Togekiss, and Hawlucha in OU, the only common Pokemon of the aforementioned Pokemon being Mandibuzz and Chesnaught, with Heracross and Togekiss being a little less common. Krookodile's Knock Off cripples any of the Pokemon aforementioned bar Heracross and Hawlucha, as the lack of Leftovers, or Life Orb, in Hydreigon's case, really sucks. Taunt + Knock Off also effectively breaks Stall, especially Chansey. Krookodile also has access to a variety of support moves such as Stealth Rock, Taunt, and Dragon Tail, while it can attempt to pull off an offensive set thanks to Moxie. Moxie Krookodile has fallen out of favor from last generation, but this by no means means it is bad, as with 252+, it hits 466 Speed, outspeeding all base 90 Scarfers and every Pokemon unboosted bar Deoxys-S. Krookodile can also provide Pursuit support, although it is outclassed in this regard by Tyranitar.
However, Krookodile has many crippling flaws that hold it back. Firstly, 92 Speed is a bit lacking for offensive sets and isn't too amazing for non-offensive sets. Next, its Special Defense is really bad, with only a stat of 70, leaving it vulnerable to many special onslaughts. It's typing also gives it many common weaknesses such as Fighting-, Water-, Ice-, Fairy-, and Bug-type moves, along with the not as common Grass-type. Krookodile also suffers from four moveslot symptom, wanting to have any of Stealth Rock, Knock Off, Taunt, Earthquake, Stone Edge, Pursuit, Stone Edge, and Fire Fang for Ferrothorn and Skarmory. Krookodile's Attack isn't too awesome without investment as well, which can leave it set up on Pokemon even with Taunt. Krookodile is also shut down by Taunt, although it runs Taunt itself, many faster Taunters can prevent it from setting Stealth Rock or using its own Taunt. Krookodile's main issue is the weaknesses it haves, which really hold it back. Finally, Krookodile is often outclassed by other Ground-types such as Landorus-T (its main competition) and Hippowdown defensively, and Excadrill and Landorus-I offensively. Overall, though, Krookodile is a very good Pokemon with a really good niche, but it somewhat struggles in the current metagame and is left outclassed often, for these reasons, I think it should move up to
B- or
B.
Gengar: A Rank -----> A+ Rank
Gengar is one of the best Pokemon in the OU metagame. It is very versatile, has three immunities, and looks badass as fuck. Gengar has two main sets: Utility Attacker and Destiny Bond. Let's first talk about the utility attacker set. This set focuses on Gengar playing mindgames with Substitute and truly breaking stall with Taunt, while also crippling many things with Will-O-Wisp. Shadow Ball is a very spammable solo-move as it is resisted by few types this generation and is just a great move in general. This set is easily Gengar's best and works so well in the current metagame. Next, Destiny Bond. Destiny Bond is a great set, being very powerful with Life Orb, and, thanks to Gengar's high base Speed, almost always guarantee one or two kills. Shadow Ball and Sludge Wave get great coverage, and combined with Focus Blast, give it flawless coverage and power. Gengar also has a lesser known set I'm fond of: TrickScarf. Choice Scarf Gengar outspeeds so much shit and can Trick it away to cripple a ton of things, while be a surprise Destiny Bond to prevent sweeps such as +1 Mega Charizard X and Choice Scarf Terrakion. Gengar has three great immunities: Ground-, Normal-, and Fighting-type immunities, while resisting Poison-, Bug-, Grass-, and Fairy-types, which can come very much in handy. Gengar is just so versatile, fast, and powerful, and has truly lived up to its being of being one of the very few Pokemon who's been OU for six generations in a row.
Now, Gengar's shortcomings. Gengar is, to put it bluntly, piss-poor bulky. It's about as bulky as paper when it comes down to it, having 60 HP, 60 Defense, and an
ok 75 Special Defense. Gengar struggles to fit all the moves it wants into its moveset, and it also lacks recovery, which really sucks when in conjunction with Substitute. Gengar also
hates Pursuit, a common move, and with the omnipresence of Bisharp, Gengar took a massive hit. Gengar doesn't take any priority, it simply cannot take any. Gengar's general weakness to all Dark-type moves also sucks, along with the weakness to Ghost-type moves. Gengar can't even switch in on many neutral hits as well, which makes it troubling. Finally, Gengar is left outspeed by many common Pokemon such as Greninja, Thundurus, and Noivern. Overall, though, Gengar is so versatile, strong, and a very potent threat in OU, and for these reasons I believe it should move up to
A+.
