Nida solo top, corki+sona/taric bot (support obv babysitting) amumu jungle, and malz ap carry mid.
Nida will 100% win toplane after lvl 6 and will have huge map controll due to her traps, when it goes down to lategame and you really need that dmg output from corki she will obv be playing ap and heal 2/3 of corkis hp. This along with sona. Corki is just an amazing ad carry whom has 2 attacks that scales with ad, that would be his machine gun and rockets. also he has great mobility when it comes down to teamfights.
Beringing us to teamfights this team comp is outstanding aswell, the cc of amumu ult and sona ult will keep the enemy in place.
And thats where malz does his thing, puts down that pool and just keeping them spells comming.
Also nidalee is really sustainable in teamfights and hes quite a bit of burst dmg.
Poking, this team wins poking battle all day aswell, we have a Corki just trowing out missiles and a ap nida throwing spear all the time.
This combo is the best imo.
