Breaker. Same way for Eze, Magress and Selena.

Reason is that Vargas, Selena and Mags' spheres already provide an HP boost.

Also, breaker for Mags because he has HP drain, high DEF, DEF ignore chance. Breaker for Selena bec. she has AI buff on ES, & HoT w/Lexida.

While Eze is only good for damaging, like Mifune, so to maximize his potential damage, go with Breaker.
