Disabler, Escape, Initiator

ARE YOU KIDDING ME?

A team composed of 5 of the 6 following heroes wouldn't be bad...but certainly can't compete against a team that has all the aspects in their heroes. In this team, you have one of the best carries in the game (Faceless Void), you have Batrider who can initiate just by blinking, stealing an enemy and using his force staff back for an easy pick up. Puck is really interesting, he can definitely help the team but you need good micro skills to play him. Storm Spirit can be annoying most of the time but I don't think he would do the job. It always depends on the enemy heroes. Naga Siren can be a really good pick, the song can always save your entire team. Siren is often seen is pro games so I don't know why you wouldn't consider picking her. Now I think Mirana is kind of useless at this point...don't pick her.

In conclusion, I think this team has too many mid heroes and needs a good support (except if you play support Naga Siren...it's reasonable). If you want to stay in the escape/disabler philosophy, I would recommend a nuker like Timbersaw offlane and maybe a jungle Lifestealer (Naix) to fast travel in allies using his Infest. A team like Timbersaw, Lifestealer, Naga Siren, Puck and I'd say maybe a Weaver or a IO (Wisp) would be pretty good.

-Puck (middle)
-Lifestealer (jungle)
-Timbersaw (offlane)
-Wisp and Weaver (safe lane)
-Naga Siren and Weaver (safe lane) --- if you play support Naga Siren
-Naga Siren and Wisp (safe lane) --- if you play carry Naga Siren

*Timbersaw can always go middle and Puck can go offlane, depends on the enemy team lineup.

?

Any aggresive trilane will destroy wisp+weaver with the LS jungle. It only works in pubs. Even a good dual lane can.

Yeah just forget the wisp...I was just trying to fit him in the escape/fast travelling heroes.
