This player has risen in leaderboards in 4 days to number 1 spot.
I believe the name is (as well as Fortesque3025) an auto generated XBox live name and given their skill and anonymity they’re probably secret smurfs of the genesis finalists. Kasva, Viper, Hera, Vortix and Marinelord all actively play on accounts with their name and RecoN plays on wutevzz which leaves Lucifron and Mista with no account they played on in the last week.
So I would assume they are the owners of the accounts in question and looking at the masteries I would guess that Creativity is Lucifron and Fortesque is Mista.
