This is the teleporting bomb which is based on a massive aoe gank, which when used properly, is extremely hard to counter. Galios AOE Taunt >>>> Amumu's AOE Stun and Nunu's AOE Slow >>>> Followed By Kennens AOE ant Trundle for the support dps. When used correctly and with the right timing can easily take out a 5 man team and still have enough health for the team to push towers without the minions!
