I used huge power perish song with wide lens. It bluffs an offensive set better and the biggest downside to the trapper azu is missing whirlpool and revealing your set. Play rough is near 100% accurate. I dont like aqua jet as without cb or belly drum the damage output is poor.
I paired it...
I used skypenguin's Dracovish set against a stall team and it worked like a charm.
Protective pads stopped the poison and he just ate fisheous rends until he forfeited.
