Skuntank

Despite not being especially powerful, bulky, or fast, Skuntank is one of the most influential Pokemon in the NU metagame due to the Pursuit support it provides. By removing opposing Psychic-types such as Slowking, Gardevoir, Grumpig, and Hypno from the match, Skuntank opens the door for NU's dangerous Fire- and Fighting-type attackers to sweep uncontested. On top of that, Skuntank's STAB Sucker Punch is one of the strongest priority attacks in the tier, and it also has access to Explosion, ensuring that it has plenty of value even in matches where your opponent doesn't have any Psychic-types to trap. You won't see Skuntank sweeping teams singlehandedly or walling all of your opponent's attackers, but it offers such unique and important support that it's worth considering on nearly any team.
