The previous Alliance roster left to join Team Liquid, who only managed a fourth place finish in Rotterdam after falling in the Losers' Round 2 match to eventual finalists Demon Slayers.
Orgless squad Demon Slayers came all the way through the North America Open Qualifier to face Alliance in the best-of-five Grand Final.
The North American and Brazilian underdogs went 2-0 up after a first map brawl lasting nearly an hour and the second match over in under 25 minutes.
On the edge of defeat, Alliance clawed it back to win the next three in a row to emerge victorious. The final match saw Alliance win four of their lanes as Top saw a draw between Neta "33" Shapira and Demon Slayers' Guilherme Silva "Costabile" Costábile.
With the win under their belt, Alliance have no time to rest as ESL One Hamburg begins on 22nd October. After visa issues hit Southest Asia Qualifier team Geek Fam, Alliance were brought in as a replacement less than a week ago.
Groups are yet to be revealed but we may see both teams in the same group compete for Upper Bracket spots in the playoffs.
Team Liquid received a direct invite to Hamburg so there is a chance we see the two rivals clash in Germany after Alliance beat TL in the MDL Chengdu Major Europe Qualifier earlier this month.
Both teams will also be in China next month following that qualifier, with Dota Pro Circuit Points and pride on the line for both rosters and organisations.
ESL One Hamburg takes place on 22-27th October and the first Major of the 2019/20 DPC Season, MDL Chengdu Major, will run from 16th November until 24th November.
