Weight rules. Height is second.
Beyoncé/Nicki Minaj head-to-head.
Basically this.
Expanding on my thoughts on it:
I think Ratajkowski is a complete non-factor in the fight. She gets taken out quick. Gal could probably take down Beyonce or Minaj one-on-one, but the two of them at once is too much for her.
I think it'd come down to Beyonce and Minaj taking down Gadot together, and then facing off with each other, with Minaj finally coming out on top.
