There are many rumours rn but it seems that frod have more freedom to build MIBR team. Why I think that? Because of that interview: https://vspace.gg/entrevistas/frod-nao-descarta-estrangeiros-no-mibr-mas-ve-como-dificil/
In this interview he said that MIBR tried to hire foreigners to their team last year and they might look this year as well, but it is difficult. He said that is irresponsible to not look for the market right now but he's satisfied with the current team. And he would like to hire more staff to the team, but only if they have similar views.
MIBR last year didn't want to spend on hiring players, that's why the team was that budget. They made tryouts with MANY players (dgzin, qck, yay, xand) and their final roster was their last option, which was the only final choice because it was the cheapest.
And according to Noyn, MIBR is looking for Cauanzin and they don't discard playing with a mixed roster (brazilians and foreigners), and because Riot will revaluate the franchise teams they might want to build a more competitive (and expensive) team this year.
