Crawdaunt obliterates any wall that dares commit the simple crime of being slower than him. Crunch packs extra punch on things that you've been obliged to knock off with your other pokemon or megas, but the star of the show is Usually Knock off. With Polietoed rain up his crabhammer reaches such ZOMG power that it 2HKOs skarmory through roost. Aqua jet is good on pokemon that have been weakened, which is easy for a water team to provide between its hazards and bulk. Anything cabable of living him will find itself hard pressed to outwall your own team without their items. ANY Azumarill is outsped, and while you don't get to use the 2HKO against competent opponents, clicking knock off means that they can never belly drum, since the sitrus will not activate to put them where they neeed to be. Most Clefable are outsped easily, and the fastest of them typically quit at neutral uninvested base 70s, so you even get insurance against cancer, who will be weakened to the point that you're almost guranteed to have something on your team to KO it with, even if it's mandibuzz. It can even go ham on mawile on certain occasions, although it's bulk is bad enough for the resitant sucker punch to kill with klefki's spikes up or after mawille is boosted.

It JUST retains the power to prevent azumarill from getting a belly drum. IF clefable (65-75%) or mawile (75%-85%, still a 2HKO with intimidate) wuss out, then you get 75% on klefki, and because it never runs speed, you can aqua jet to KO before it sets up reflect or twave, meaning you will still get 1 of the other 3 trades, any of which would put them in kill range of many of your other pokemon even if they did get screens again .
It's almost entirely outclassed by the band set against other teams, as few other monos share resistances to this pair of stabs, although it means they cannot revenge you with weakened pokemon anymore due to being able to switch to priority at any time.

Crawdaunt can set up with one of two moves.. While he dosen't outspeed much, (see below) it has it's uses. The SD set is usually better, as aqua jet is the most versatile attack, and at +2 it can break several frailer pokemon with just a touch of prior u-turn, sandstorm, or hazard damage.

Crawdaunt falls short of base 60 so he only edges out base 105 (unevolved manetric anyone?)+natures rather than the all important base 108 + natures or the 110+ lati twins that a base 60 scarfer could get. However, in exchange for giving up sheer power, he can hit crippling threats like mew before they status him, trick people, or whittle down a pokemon that your team just needs to not exist in order to function. He's also wonderful because if he KOs something in a neutral match up, they are almost guaranteed to reveal which of their own pokemon is scarfed, which can be huge if it was something that you didn't expect, or at the least, allow you to bring out a brick wall and freely hazard/phase/status when it runs away again.
All in all, Crawdaunt is comparable to the crash novas you found in old arcade coin op games. He clears the screen and then his blaze of glory burns out just as suddenly. Water teams suit him extremely well because he can ward off habits of safe switching between important walls and get rid of the one things per team that typically threatens to have the ability to disable the defensive core for good. Slow rotom w volt swtich and vaporeon baton pass can even get him in easily. If your wondering, Life orb adamant knock off still JUST stops azumarill from using belly drum, for those of you afraid of letting in mawile, who is still 2HKO by crab hammer after an intimidate.
