King Crab - A discussion on cards that tech against themselves

I love the crab "hate" cards because they are decently powerful tech cards, but not overbearing. They also target a specific archetype (murloc, pirates, etc.)

People have mentioned a "crab crab" on this sub before--a crab that eats crabs. This leads me to wonder if such a card would be feasible. Instead of teching against an archetype, it would be used to tech against tech cards.

The other element that would make this interesting is that it is vulnurable to itself. I might play Golakka, you crab it, but then I turn around and crab your crab right back.

Would this be an interesting concept? Or is it just a meme? I would like to hear your thoughts.
