Dota 2 New Heroes with Insights and Previews [Dueling Fates]

During the International 2017 Valve release about the 2 new heroes joining the dota 2 hero pool, Sylph and Zorros.

What can these 2 heroes contribute to the meta we have right now?

First, Zorros, as you can see must be an agility hero with a rolling skill as can be seen in video, you can also see that he removes some quills in bristleback, maybe he got a passive skill that can "break" hero abilities like bristleback's brislteback 😁. This ability can only be seen in the item "Silver Edge" which removes passive abilities of an hero for a period of time.

Next is Sylph, there is no much preview for her in this video but you can see that she summons something, she might be an intelligent type of hero that has a summoning skills like beastmaster. There is also a rumor that she is a wind type hero that has a damage burst from her skills, who knows. 

Only valve knows what is their ability and types, in a few months maybe we will see this 2 new heroes in the game.
