No, not that box.
I mean a different, creepier, far more awe-inspiring box:
Kejila, the Hidden Horror!
Besides looking like an accordion with a thyroid problem, Kejila is one of the best users of the new ability from Shockwaves: Silent Skill. If it's been tapped, it can break two shields without having to attack. A good strategy would be this: on the turn when Kejila can first attack, incapacipate and/or destroy of all of your opponents blockers, then have it break two shields. Then, it can use Silent Skill and break two more shields, effectively making it a Quadruple Breaker.
It works good in, interestingly enough, a Dark/Light deck. An all-tapping card like Holy Awe can help Kejila break its two shields (the ones via attacking) without being blocked. Of course, it also helps to have a big dude like, say, Kuukai, to help eliminate all attacks on Kejila. And, if a big enough attacker should arise to be able to get past Kuukai, just be willing to sacrifie Kejila, as it's a better alternative to losing shields. This card is a great asset this way, helping you to win a game by completely turning the tide of a battle.
Ballom's Rating: 4/5. While Kejila has an awesome effect and look, it has low power, high cost, and a large amount of blockers can hinder Kejila a lot.
