Had a 73 win streak before I lost due to stubbornness and not paying attention to abilities. I might have been able to keep going if I hadn't started playing in the middle of the night since I couldn't sleep...
UFSW-WWWW-WWW3-ANBZ
It was a double battle team:
Talonflame - Adamant - Gale Wings - Choice Band
252 HP/252 At/4 Sp
Brave Bird
Flare Blitz
Steel Wing
U-Turn
I don't think you will use Acrobatics, so I would suggest adding U-Turn instead in case you ran into a Tyranitar. Use Steel Wing over Flail for a bit of coverages and to deal with Rock Type Pokemon, it would be rarely useful, but it can at least be helpful in some battle. And yes Talonflame is OP lol (make me comeback in Wifi Battle).
I don't even know why I have Flail or Acrobatics on there. 90% of the time you'll just spam priority Brave Bird on everything, and if it'll deal heavy damage to anything that isn't a rock or steel type (even electric types, since they have poor defense) and you'll be able to finish it with the partner Pokemon, and it can K.O. anything weak to flying or neutral and has poor defense outright. Since you'll have both high base speed and priority most of the time, speed EVs were instead placed in HP to boost survivability. Just keep it away from rocks.
Honestly, a priority BP 120 attack just isn't fair.
Absol - Adamant - Super Luck - Razor Claw
4 HP/252 At/252 Sp
Night Slash
Psycho Cut
Megahorn
Sucker Punch
Maybe I haven't looked hard enough, but I haven't seen anybody abusing the changes made to the crit rate this generation. Super Luck+Crit Item+Crit Move=100% critical rate, and a Megahorn or Sucker Punch with a 50% critical rate is downright scary. Absol can survive a hit from Hydreigon and one shot it with Megahorn, finish off threatening attackers that Talonflame weakened with Sucker Punch, deals heavy damage to fighting types with a critical psychic attack, and laughs in the face of Curse Steelix with guaranteed crit neutral STAB attacks. Most of the time Absol can survive one hit as long as it isn't weak to it, which always surprises me.
Azumarill - Adamant - Huge Power - Sitrus Berry
4 HP/252 At/252 Sp
Aqua Jet
Play Rough
Super Power
Belly Drum
The moveset is good, but I would recommend Sitrus Berry for item, since it will increase survival chance after a Belly Drum.
There isn't much to say here. Azumarill is the premier dragon slayer on the team, and plays an important part in beating steel types with Superpower. Belly Drum was used more often before I could afford the life orb, so it may be worth trying to replace that with something else.
Scizor - Adamant - Technician - Scizorite
4 HP/252 At/252 Sp
Bullet Punch
X-Scissor
Aerial Ace/ Brick Break/Rock Smash/Superpower
Roost/ Sword Dance
You can replace Roost with Sword Dance if you want to increase the chance to OHKO opponent with Bullet Punch. If you think Steel Type will wall Scizor completely, then use Fighting Type move to deal with it.
Yes, every single member of the team is an adamant priority user. It was kind of a theme I had going when I was designing the team. Anyway, the set is pretty obvious, using technician boosted bullet punches for heavy priority damage, and X-Scissor and Aerial Ace against slower enemies when they were most useful. Aerial Ace has the added bonus of ignoring brightpowder and double team hax. Roost is situational, but there is the odd occasion it is useful.
Considering it's a team I didn't put too much thought into (my thought process amounted to 'what are the most powerful priority moves I can cram into one team?') I don't think it did too badly, especially considering it lost due to repeated misplays against legendaries, instead of hax. I guess you could replace megahorn with play rough for better coverage and accuracy, among other things, I'm fairly happy with it. Major weaknesses would be steel types (only Azumarill has a super effective attack, since Talonflame is usually locked into brave bird, and they wall M-Scizor completely) and the lack of defenses on the leads.
