I reached a streak of 108 in Super Singles using a simple team i threw together. I don't know how to post a pic, because i don't know where to confirm the streak xD. Will post if someone can tell me where it is.
Anywho, here's my team i used:
Lucario @ Focus Sash
Adamant Nature / Inner Focus
31/31/27/x/28/31
4HP/252Atk/252Spe
Moves:
Swords Dance
Extremespeed
Close Combat
Crunch
The Set-up Powerhouse of the team. He leads off the matches, and depending on who I'm facing, I use certain moves to get the greater advantage. If the opponent isn't bulky or fast, I use close combat for the immediate kill. If the opponent is bulky, not fast, and doesn't carry a priority, I use Swords Dance. If the opponent has Focus Sash/Sturdy, i use Close Combat+Extremespeed. There are exceptions, but this is generally the case. Lucario is used over other fighting types for his steel typing, which gives a surprising amount of switch-in opportunities for...
Hydreigon @ Choice Scarf
Modest Nature / Levitate
31/31/25/31/31/31
4HP/252Sp.A/252Spe
Moves:
Draco Meteor
Dark Pulse
Surf
Flamethrower
Hydreigon can be summed in use of my team in one word: Insurance. I Use Hydra for his diverse movepool, Dragon Typing, and nice Dark STAB. I try and limit my uses of DMeteor, for reasons I'll post after the team. His Dragon Typing pairs well with Lucario's steel, switching in to ground and fire moves with impunity. And to round off my team (and ensure Stallers don't beat me)...
Milotic @ Leftovers
Bold Nature / Marvel Scale
31/x/29/30/31/8
252HP/216Def/40Sp.D
Moves:
Scald
Toxic
Ice Beam
Recover
Ahh, before I tried Milotic, i thought using a wall in the Battle Subway was stupid. After, though, he turned out to be the most useful member. I run Scald over Surf for the Steels and poisons that are immune to toxic. Ice Beam is to take down pokemon faster that resist scald. Recover is obvious, it's there to increase longevity and aloow me to burn/toxic stall.
How I lost: Draco Meteor's 90% accuracy shows at many crucial points in runs, but this was the worst, since i could have avoided it. The match started off against a Togekiss, whom my Luke hates facing due to TWave. I switch to milotic, who does in fact get Thunder Waved. I use Toxic to start whittling it down.Afterwards, though, Togekiss gets 4 flinches in a row with Air Slash. I don't want to get milotic too weak in case i need her later, so i pull out Hydreigon, who gets in rather nicely. This normally wouldn't matter, he has a decent special bulk, but then Draco Meteor misses. At this point, I'm mad, as damage calcs show that Dark Pulse was suffice for killing, but instead, Kiss uses TWave. I use DMeteor again to kill Kiss, then Jolteon comes in. I was in the car on a trip to Kentucky, and i had never faced a Jolteon in the Subway before, so i assumed i could switch to milotic, take the coverage hit, and then switch back to Luke to set up and sweep...the coverage move was Signal beam. Milotic comes in, to die to Thunder afterwards. I send in Lucario, use swords dance as thunder hits hard, and i get paralulz. I think that a +2 Extremespeed can OHKO Jolt, but just to be shown, Parahax sets in as thunder delivers the killing blow. Hydreigon, ready to kill, comes in again, and i select DMeteor. It misses yet again, and Signal beam KOs my Hydra.
And that is how i lost my 109th battle. I've tried more runs after this one, but each time i am forced to use DMeteor to have a chance of winning, just to miss.

Sorry for the crappy quality, only have my comp's built in webcam, and they're never the best.
