This has a 27 win streak: https://www.warlight.net/LadderGames?ID=3&&LadderTeamID=9016&Offset=0

I believe the old record was 26?

Taking nothing away from Wohoo, that is very hard to do...but fatality streak looks much harder opponent wise

Yeah, not easy for sure, yet only two opponents >1900 rating and TeddyFSB being the only signature win there ... What fatality and especially Latnox did (https://www.warlight.net/LadderGames?ID=0&LadderTeamID=2231) - who had 28 straight wins btw., so no new record here - was much more impressive indeed because of the opponents they managed to beat.
