Focus on dealing with 2 types, eithet energy and phis, or heat and phis.
Neither will fair against phis, because low averall hp, and no resist.
I rekon you dont have phis protector, so your best shot it hp.
For that you should use 3 plates, and set it up as a heat-phis fighter.
So back on the first build you presented :
Drop an anih, put seraph(65-49=24kg spare), drop a heat engine, put a booster, +10kg spare, drop teleport, another 11kg spare. Total spare 45kg, put another plate.
