Wimpod

Thanks to access to Spikes and Taunt as well as having a great Speed stat, Wimpod can function as a decent suicide lead on offensive teams, as it is the fastest user of Spikes. Thanks to its 18 Speed, it can notably outspeed every common lead in the metagame, including Onix and Dwebble. Its ability Wimp Out allows it to usually get up one layer of Spikes and immediately give a teammate a safe switch. This can give your team a lot of momentum, and in combination with Spikes can put your opponent on the backfoot from the start of the game. However, Wimpod's stats other than its Speed are bad, meaning it will be knocked out easily and unable to do much damage in return. In addition, its movepool is very lacking, making it struggle to hit Pokemon that aren't weak to its STAB moves. This makes it incredibly passive. Wimpod's typing leaves it weak to Rock, not only meaning it is weak to Stealth Rock but also that it loses to common leads like Dwebble and Onix. At the same time, Wimpod faces a lot of competition from these Pokemon, as they have greater bulk and can set up entry hazards more consistently thanks to their less situational abilities, though Wimp Out does give Wimpod a small niche. However, Wimp Out can also be a curse, as a faster Pokemon can easily knock it below half HP, thus forcing it to switch out, meaning Wimpod cannot get up a layer of Spikes. Since it is unable to do much other than set up Spikes, Wimpod is very predictable, and opponents will thus easily be able to see its lead coming. Lastly, after it has been forced out because of Wimp Out, it struggles to get back in due to its weakness to Stealth Rock and general frailty.
