fnatic doesnt play like astralis, astralis plays very organized and plays lots of defaults while fnatic likes to give their players flexibility and do uncommon plays. while mouz definitely have the firepower, i dont think they will be prepared for these odd rotates and pushes. unfortunately for fnatic this is a bo5 and they can only ban 1 map, which means that maps are equal but slightly favor mousesports. fnatic are better as a whole, while mouz has the one or two gods carrying the team. because of this, i think its fairly even, but my gut instinct says fnatic because we see them often going down first map then pulling off sick clutches and comebacks. we will see tomorrow though.
Prediction: Fnatic 3-1 / 3-2 mousesports
I think if fnatic get first 2 maps they are off to a good start, they have a buffer for the maps they arent as good at.
