Valeska is an Archery focused hero, obviously, and want to know fundamental strategies and tips for making her as good as possible.
If you do not know much, sharing information from Youtube or such would be great.

Personally I just use her as a starter hero for more archers, but switch to a proper main ASAP. Obviously Orrin is the best (assuming you're playing Hota / or Mullich is banned) but getting a Barbarian/Beastmaster is also neat.
