Well, this was my team.
Azelf is a very good lead which can ohko many Pokemons (or at least 2ohko) and its fast at the same time. Explosion for making huge damage. When the opponent had a weavile lead (which I saw many times), my Azelf first took a hit and attacked then with flamethrower. The Weavile usually had a Focus Sash, so it didnt die and I swichted in my Lucario. Night Slash or Ice Shard didnt hurt Luce at all and I used Xspeed to finish it off. I think it was very important to keep especially Azelf alive.
Then my opponent often swichted in something like Garchomp or Donphan (I dont know anymore xD) to ohko Lucario with Earthquake. You can just switch out easily to Azelf to dodge the attack. I realized that the opponent didn't predict at all.
Garchomp @Scarf is faster than many Pokemons and can ohko many sweeper with Outrage though it was risky to use that move at some point xD
I believe Lucario was my key Pokemon :O
When the opponent had a Umbreon/Suicune/Cresselia I immediately switched in my Luce and used SD as many times as it can. Toxic dont affect Luce and Payback/Icebeam dont hurt Lucario very much. Also they used Protect and such stuff which gave me a free turn to set up. After that Lucario swept the hole team with Xspeed. That was fun :D
This team had a very good type coverage Garchomp Ice--->Luce | Luce Earth--->Azelf Azelf---> Everything expect Ice moves---> Garchomp, since it's bulky enough to take a hit and its very fast and powerful at the same time.
However Mamoswine (especially in a hail team) was IMO the biggest danger for my team. It was often the last (third) Pokemon and it was able to ohko azelf (which of course often had only 1hp) with ice shard and ohko lucario with earthquake (Xspeed did maybe 45% damage..I dont know any more). Also it always nearly ohko'd my Garchomp (full hp) and it survived with only 2 or 11 hit points.
Btw I noticed that from rank7 many player used Scarfed Togekiss with haxpower (air slash) or Scarfed Latios with Draco Meteor.
English isnt my first language, so I must admit that it wasnt too easy to explain everything in English and I am sure I made many mistakes xD
However I hope you understood more or less what I wanted to tell you and had fun
Congratulations on the second-highest legit streak we know of (sorry Peterko but pretty much no one I've talked to believes your German friend's streak)
Well, its really unbelievable but I am sure his streak is legit. He's a cool guy. Why should he lie..oh well ;D
