It has bad stats and the roles it tries to perform are too varied and too compressed. It wants to be a physical attacker, a special attacker, offensive utility, and all sorts of things but it doesn't have the stats to pull any of them off in a serious competitive setting.
With this spread, it becomes very aggressive. You can choose to run Toxic or Toxic Spikes on it in order to rack up poison damage, or you can use a more typical set of Taunt and three attacks, and rely on teammates for Toxic Spikes support (if paired with Toxapex, or on a Mono-Poison team in gimmick formats).
Merciless coupled with Sucker Punch and Pursuit means if the opponent is poisoned, you can play "will they or won't they" mindgames and flip a coin to get big damage. With this much speed, you might even drop Sucker Punch entirely and just come in on things you already outspeed.
Honestly, I don't know if it's even good. It needs a lot of support to function and as a basic "fast physical attacker" it's facing a lot of competition from Mega Lopunny, or even a lot of scarfed attackers.
