Barraskewda

With one of the fastest natural Speed tiers in the metagame, Barraskewda is an excellent pick for a wallbreaker that can easily pivot out of its checks with Flip Turn, dealing decent chip damage to most Pokemon, and clean up late-game with its stronger attacks. On rain teams, Barraskewda turns into an incredibly powerful threat that is practically impossible to outspeed thanks to Swift Swim. However, Barraskewda suffers from the presence of common Water-resistant Regenerator Pokemon like Slowbro and Amoonguss that can shut it down and render its attempts at wallbreaking useless. Barraskewda is also quite frail and can be easily forced out, which can end up giving strong wallbreakers such as Basculegion-F and Hisuian Lilligant more opportunities to blow holes in Barraskewda's team. Thus, Barraskewda often relies on offensive partners to break through its checks and counters and defensive ones to restrict opposing wallbreakers from taking advantage of it.
