(a couple versions of) A card that counters the card countering crabs.

I've been recently thinking that we're missing a Beast counter minion and thought it would be ironic to make a card that would counter the crabs. It's important to me that it does 4 damage so it can kill both kinds of crabs.

I made a couple different versions, which one do you guys think is better/more balanced?

I don't think we need a beast counter. Beasts aren't really very strong, and the only class that synergizes with them is Hunter. Hunter is bad right now, and putting this in would debuff a class of cards that already struggles to be viable.
