I'd cut
Hour of Need, if I were you. It's rarely good to spend two cards just to get a 4/4 flier, and it's really bad as removal.
If you want to change more than that, it might be worth playing more Ferocious enablers. You don't have that many. To make room you could probably cut some of the more situational payoffs, like
Feed the Clan and
Winds of Qal Sisma. They have the potential to be great, but they also have the potential to be blank cardboard.
Force Away might also be worth dropping. It's just generally low-impact.
The maybeboard cards that most appeal to me are
Stubborn Denial and
Ashcloud Phoenix.
