My 8 teams that I have for the first challengers event are
100T, SEN, C9B, V1, TSM (this one is hopeful LOL), ABX, NV, (LG/IMT/FAZE/GEN G/) - This last slot is unknown for me bc of their roster changes. but i do predict that from this challengers, the 4 teams that will succeed and qualify to the playoffs are 100T, SEN, c9b, and nv/tsm
