For summoner spells take flash and ignite. Early game ziggs is very powerfull. Abuse it by poking with q whenever you can and getting an auto attack in whenever your passive is up. Save your W for escaping ganks.

Ziggs is a great teamfigher. His Q is AOE, his W is an AOE knockback, and his E is a AOE slow. Best off all his ult is an AOE execution, but don't always use this to pick off low people trying to escape as it is somewhat easy to dodge. It is best to use it when you can hit the entire enemy team. Use your W to try and knock back enemies into range of your teammates.
