TSM has 2 comps right now
Karthus/Nocturne/Kayle ruin top lane for ANYONE. If Kayle can't beat you one on one(which is rare), at level 6 Kayle will shove to turret until she can whittle you down to 3/4 HP with E and minion damage and then Nocturne dives, Kayle ults, Karthus ults. Top Lane is now done. In team fights Nocturne blanks the screen, Karthus suicide dives, Kayle ults whichever one you focus, your carry is now dead.
if you ban out that combo they go Dyrus Vlad Top, Regi Kennen Mid, Maokai Jungle AOE Comp. If you counterpick Vlad top Dyrus goes Kennen top and Regi goes Vlad mid.
Very basic strategy that they execute to perfection.
