Have either a heavy tank team with nice dmg output:
e.g.
APTank Malphite: Soc Shoes, Hunting Guise, Abyssal, Sunfire + Arm/Magresi
ADTank Jayce
Lee Sin
Or
AP Bruiser Teemo: Malady, FM, DFG and stuff
Katarina: DFG + Witchcap + Abyssal and ur in
Malphite/Amumu/Alistar/Lee as a fulltank
Or a pretty nice combo:
Darius+Skarner/Teemo+Katarina
Darius+Katarina=Free CD for Kata
Teemo nad his Shrooms are wards+free jumps for Kata
Or the skarner is a killsafer, eg. darius pulls, skarner ulti and then dmg and the enemy will be dead..
Well, you need the right combo of cc, tank and dmg ofc.. but this shouldn't be new ^^
Btw Teemo ist OP on the new tt, becaus of his free wards... and slow and with kata she has nice escape mechanism ^^
/sorry for the not that well english :D
