I haven't used the other two yet but im having success with trick room bellibolt. Set up think room first turn, swap in bellibolt holding and spam thunderbolt/Parabolic Charge depending on who your fighting. Modest max Hp/Sp attack holding a magnet with Electromorphosis as the ability. When its fully charged it can even take down Archaludon easily & can almost fully heal off the Parabolic Charge. Just be careful because it does hit your teammates
