I'm finished with both Arcanine and Nidoqueen.
Arcanine
Typing: Fire
Base Stats: 90 HP / 110 Atk / 80 Def / 100 SpA / 90 SpD / 95 Spe
Abilities: Intimidate / Flash Fire / Justified
Since the inception of Black and White UU, Arcanine has been a formidable force within the tier. Although it can no longer take advantage of Drought conditions and thus loses some utility, it still has all the tools necessary to succeed in the tier. Excellent mixed attacking stats, solid Speed, reasonable bulk, two extremely useful abilities, and an amazing movepool that provides it with almost impeccable coverage while still allowing it to retain a slot for a priority move, healing, or another type of support move all combine to make Arcanine one of the best Pokemon in the UU tier. The transition to Black and White granted Arcanine access to Close Combat and Wild Charge, improving its coverage and power dramatically. These new assets, as well as its previous advantages, allow Arcanine to play a variety of roles. Arcanine is one of the most versatile Pokemon available in UU play, capable of breaking holes in opposing teams with its powerful Choice Band set, smashing walls and possibly sweeping while retaining the ability to heal with Morning Sun and switch moves with its devastating Physical or mixed Life Orb sets, and even using bulky sets that take advantage of its reasonable defensive stats, access to somewhat reliable recovery, two extremely useful abilities in Intimidate and Flash Fire, and decent support movepool, which includes moves such as Roar, Toxic, and Will-o-Wisp. Arcanine’s only significant drawback is its pure Fire typing, which, while excellent offensively, is poor defensively, giving it weaknesses to common Water-, Ground-, and Rock-type attacks, including the omnipresent Stealth Rock. Despite these drawbacks, and due to its incredible power and versatility, Arcanine is easily one of the most powerful and dangerous Pokemon in the UU tier, and is a threat that every team should prepare for if it hopes to succeed in UU play.
Nidoqueen
Typing: Poison / Ground
Base Stats: 90 HP / 82 Atk / 87 Def / 75 SpA / 85 SpD / 76 Spe
Abilities: Poison Point / Rivalry / Sheer Force
Although Nidoqueen’s male counterpart overshadows it in terms of offense, Nidoqueen has found a niche as an excellent support Pokemon. Almost no other Pokemon in UU is capable of learning both Stealth Rock and Toxic Spikes, and Nidoqueen has utility based on that alone. In addition to her incredible support movepool, including the aforementioned entry hazards as well as moves such as Roar, Taunt, and Toxic, Nidoqueen also possesses fantastic defensive typing, while also having access to STAB on one of the best offensive types in the game. Her typing provides her with important resistances to Fighting-, Rock-, and Bug-type attacks, as well as a complete immunity to Electric-type attacks, although it does leave her with a weakness to Ground-type attacks, always a flaw in a Physical wall or tank. Combined with her good defensive stats, her typing allows Nidoqueen to perform excellently as a Physical wall, capable of countering some of the most significant threats in the UU tier. Nidoqueen also does not lack for attacking options, with access to both Physical and Special STAB moves, as well as a plethora of other coverage moves encompassing types such as Fire, Ice, Water, and Rock, all of which pair quite well with her Ground-type STAB attacks. Nidoqueen’s impressive support options, good defenses, and top-notch type coverage make her a great choice for any team in need of her unique advantages, especially teams based around Snow Warning support, and opposing teams should always have some answer to Nidoqueen, lest she directly or indirectly cause their defeat.
Pending approval of these two, I would like to reserve
Cobalion and
Kingdra.
