Sneasel

In RU, there are no Pokemon that possess the incredible revenge killing and Pursuit trapping capabilities that Sneasel does. These strengths bring invaluable utility to nearly every team archetype. As a unique offensive Dark- and Ice-type attacker, Sneasel can force switches against Pokemon that wouldn't normally be concerned about Pursuit, such as Flygon and Venusaur. This capability puts Sneasel a step ahead of other Pursuit users, since it naturally threatens a wider range of targets. Furthermore, Sneasel's Speed tier and access to STAB Knock Off, among other good coverage moves, allow Sneasel to consistently revenge kill slower offensive threats or Dark-weak Pokemon, such as Mega Glalie, Sigilyph, and Jellicent, and hold its own against defensive teams. While good offensively, however, poor defensive typing and paltry bulk mean Sneasel can neither switch into nor withstand many attacks. It is also easily worn down by entry hazards and Life Orb recoil. These factors inhibit Sneasel's overall performance and prevent it from excelling as a Pursuit user.
