Only If Face Hunter can’t hold itself up against the dominant decks of the meta (which IDK).
Matchups winrate are an important part of a deck effectiveness, so If your deck has poor matchups against most other meta decks (like Tickatus locks, which prey on a very especific type of decks) it will hamper your climb.
If It does not, you can climb on It alone. You may also need to change decks If you can’t really understand How to play the deck you’re playing well. Compatibility is also important.
