This one is similar but here we have a choice banded Tyranitar with pursuit as the wallbreaker and we have Rotom Wash as the defogger instead of foul play and Gholdengo as the special attacker with hex + 3 attacks beacause we dont wase to time on recover but you could run recover if you hate Lele. Double rocky helmet to punish u-turns.
