If you're able to Power Trick and get any hits out, it's definitely worth it. But with the low speed and not-so-great HP, it could easily be taken out.
From Bulbapedia: Although the circumstances would be nearly impossible, a level 100 Shuckle can potentially deal the most damage in one single attack through the use of numerous stat boosters, by using Helping Hand, Metronome held item, Power Trick, a Skill Swap to Huge Power or Pure Power, and the Defense Curl/Rollout combo. On the 5th impact of Rollout, if used against a level 1 Ledyba or Yanma that have been hit with negative Defense modifiers (such as Screech), it can deal over 315,000,000 damage.
I'd like to point out again is that with trick Room support, you could easily sweep a good half of a person's team with Shuckle.

If your gonna use Shuckle, use it for it's defensive purposes. Power Trick combos are too risky.
