Does anyone actually use the Thunderbolt Kraken or Parrot Navigator? I've tried both of them in different team setups many times because a friend recommended them but they have never worked once! I kept a close eye on the damage various cards were dealing before and after using either of these 'weaken armour' cards and it was exactly the same every time.
If they don't work then what is the point of them even being in the game in the first place?
