Kraken can be raised three times without hitting the top. But it would be close. They would need to be lowered three times to be out of danger at that point.

Us, Yatagarasu and Unicorn can be raised three times without hitting the top and would only then need to be lowered twice to be able to be raised one more time.

But given their position, of the the teams that can be raised three times without dying, Kraken may be the least likely to be raised this round. So they may be the best choice.
