Haven't posted in awhile, thought I'd share this team I used in Snake since its been incredibly fun to use as well as surprisingly potent and effective. Crawdaunt doesn't get a lot of love and I'd like to see that change as it's a scary, albeit hard to build with breaker and cleaner in one.

Hyper Offense is a pretty fitting archetype for a glass cannon. Band is pretty much the only Crawdaunt I would ever consider using, but it's damn good at its job of functioning both as an early game breaker and a late game cleaner with Aqua Jet. Adamant forces stuff like Hydreigon to either Roost or die, gets you notable kills with Aqua Jet combined with Rocky Helmet chip on things like Terrakion. Manectric is necessary on these teams as a pivot and Scizor check, and the sheer number of Pokemon that beat Ground-types can often lead to it becoming a potent cleaner late game with them removed. Signal Beam is a cool tech here to increase the odds of me softening Hydreigon for Crawdaunt and Decidueye, while also being useful to hit Latias, Celebi, and Krookodile. Scarf Latias is only valid on HO, where its niche of blazing speed and Healing Wish can come into use, it fits the team nicely and let's me use my breakers more aggressively early. Mamo is always a solid pick for offensive teams, here im using four attacks with freeze dry to maximize my chances of softening Waters and Grounds. I find using Mamo as a rocker can limit its potential as an offensive threat and All Out Attacker sets really do it more justice. Cobalion is the Rocker and Steel-type of choice, Rocky Helmet has good synergy with Crawdaunt in chipping things to Aqua Jet range for cleaning, and Stone Edge is used here to lure Moltres which otherwise as problematic. As you Rock the Moltres likely has to to stay in to Defog, or if using a spinner they'll most likely stay in to fire off a STAB. Finally, Decidueye is the nail in the coffin for stall teams, as well as just another solid opener where you can use the Z move relatively safely early game and get huge damsge. A substitute user to take advantage of passive things like Blissey or Alomomola or even easing prediction on switches like Hard Krookodile is great to have.
A lot of the "tricky" matchups on paper for this team are stupidly easy to break, Hydreigon basically gets one switchin due to Mane carrying Signal Beam and Decidueye's Z move and Crawdaunt's STABs doing more than half a piece. Moltres gets lured by Cobalion, Latias can only really come in on sacs or Cobalion and as long as you have your own or Mamo active it won't ever sweep. No Fairy resist isn't that big of a deal as Primarina forces a trade even if you didn't have a Steel that resists Fairy.
Hyper Offense is pretty underexplored right now I think it'd be cool if other people had their own takes on what Crawdaunt can do for the playstyle n.n
