well, theorylly its good, as each 2 turns u can layout 120 dmg ! no kidding!
but the down side is, if u dont have energy each turn, ur doomed!~
and further more, to do 120 dmg each 2 turns and need to discard energy for that to happen is bad!!
why? u might ask, well, this is simply bcoz if u keep focusing only to attach energies to active octillery, u wont have a back up pkms or another octillery rdy to battle after the first one got KOed
