Playoff Seeing

Do people already know generally what the playoff matches look like? I do not know how it will work but aren't certain teams only able to play like 2-3 different teams from the playoffs cause of the different rules put into place on how playoff matches work? For example, Sen can not play TH but I also read they can not play some other teams as well (for reasons i forgot).

So do people already have a rough idea of what the matches-up could look like or am I wrong?

I like the random draw but regardless I think Sen get the side of death and will have to go through a gauntlet cause of how their bad luck with placements is.

its random draw afaik (first seeds vs second seeds), then in the second set of matches in lowers the bracket gets flipped

1st seeds play vs 2nd seeds and teams from the same group cant play each other i think
