i used two annihilator with brutality torso but opponents never tolerate me to use two of it simultaneously n its hard to catch rolling energy mech.
i suggest as per your inventory.
use night eagle n two nightfall 1 annihilator. with teleport hook charger, atleast epic multi resist, epic hp plate.
you can beat heat mech opp surely n be cautious against corrupt light. but not possible to win sometime against better fused energy mechs. you can sustain ladder between 2 or 3. 1300hp or 1500hp will do fine.
HAVE FUN !
