Quote from NZB2323 »So many things I don’t understand:
-When he was attacking with 2 BBE and the opppnent blocked with a creeping tar pit, why didn’t he let a BBE die and then return it with KC?
He pretty much explained it in the video. The opponent had 2 cards in hand at that point, and he wanted to make him discard those 2 cards with KCommand and Lili. As soon as the opponent played Bolt on one BBE, there was only 1 card left in the hand of the opponent which means KCommand could use other modes. Killing a creature and saving one own creature makes more sense than letting BBE just trade and deal 2 dmg to the face. That way you don't reuse BBE, but you just save her as a creature and get back Bob, which is essentially making the KCommand more valuable. Its 2 dmg to the face and recur BBE vs. Kill tarpit and recur Bob. The latter is more value with KCommand.
One thing he could have considered though was to let BBE trade with tarpit and then in the drawstep of the opponent discard + recur.
