Whole deck revolves around getting Shellfish.
use Tracking to get it.
Only ever use Pet Collector after you've first used Dire Frenzy on your first clam.
Be careful to not trigger parrot on other deathrattles, like the Saber.
If you can get brann and a parrot, that's 4 cards your opponent has to draw.
Mostly this deck just gets silly 13/13 clams if they can't keep you under control, which is also fun!
