Two fairly unknown teams are doing their best to move up in recognition, and are after that sweet, sweet cash prize. First they need to find out which team is the best.
Nz1 goes with Swiftblade and Soulstealer for carries, with Pestilence for initation, Demented Shaman for support and Pyromancer for AoE damage and strong ganking potential.
IPL goes Madman and Forsaken archer for carries, with Magmus for intiation, Plague Rider for support and Pebbles for AoE damage and strong ganking potential.
Wait... those two paragraphs seems pretty similar. As you can see the team lineups are similar, we're not seeing a tri-carry versus pusher strat or anything. Both teams put a melee carry and their support in their short lane, but Nz1 puts Soulstealer mid while IPL puts Libertine playing Pebbles there. It pays off for them, as Pebbles unleashes his combo on the squishy Soulstealer as soon as he hits level 4 and gets the bloodlust kill.
About a minute earlier, `Cujo's Forsaken Archer almost got picked off early by Demented/Swift but ran into the tower to deny Nz1 the bloodlust kill. IPL starts off very strong, a 6-1 lead at the 5-minute mark, leading in farm and gold. Pebbles is roaming around the map, ganking and Forsaken Archer is building up her farm.
Nz1 is down but not out though, some coordinated ganks of their own get their Soulstealer some much needed kills, but Swiftblade isn't gettign any luck, sitting at 130 gold per minute with a 2-5 kill score. With Forsaken Archer at 8-3 and over twice his farm, Nz1 has to rely on Soulstealer. And he's getting routinely ganked by Pebbles, his Portal Key initiation so dangerous.
After killing off their carries they make a push, and increase their lead even more, 28-11. The level and farm advantage is too big at this point, and a Kongor kill and one final push makes Nz1 concede just before the 30-minute mark.
Game 2: Match ID 8103318
Nz1 starts this game with a Pharaoh pick, going up mid against IPL's Valkyrie. Andromeda and Arachna go top against IPL's solo Thunderbringer - leaving a trilane bottom consisting of Slither, Demented Shaman and Chronos, which Nz1's Pyromancer and Magmus has to deal with.
The early game is a lot more even this time around, both teams getting in decent ganks. However, IPL is running away with farm, both TDA101's Valkyrie and `jitters Chronos over 200 gold per minute, which none of Nz1's team have.
Valkyrie is rapidly running away with the game, Nz1 never succeeds in killing her, and she pushes lanes, kills heroes, attacks towers, all kinds of good stuff. She's sitting on 369 g/m at the 16-minute mark, already with a Firebrand and three levels ahead of anyone on the opposite team. At the 17-minute mark, Chronos is about to get caught by the Magmus/Pyromancer combo, and decides to use his ultimate to escape, but it's not enough! It runs out with half a second left of the homecoming stone channel, and Magmus stuns him. All looks lost, but Thunderbringer's ultimate kills Pyro, and Valkyrie's ultimate hides Chronos, letting him escape.
After a dominating teamfight at the 23-minute mark, IPL picks up a Kongor kill and prepares for a strong push. They Genocide the enemy team in the next fight, takes down a tower and both barracks, and it's all inevitable from there. Nz1 GG's at the 30-minute mark, and Interpol wins the Qualifer Finals 2-0.

Best of luck in the playoffs to both teams!
