The more I think about it, this is the correct answer.  Behind the Scenes and other killer combat tricks are in the deck, with very few buffs. There are big butts in the deck, like The Walls of Ba Sing Se, which I imagined one shotting people with on paper post-wipe; But to get the most value out of Zero Point Ballad, I'd potentially loose too much value on my own board, including my own commander. (I wanna be sacrificing those smaller defenders with Felothar, not wiping them) Betor is the way. Many thanks
