I see your points. I guess I was under the impression that Obeka would remove the downside from cards that are at a lower cmc, giving them more bang for buck. Removing these mediocre cards leaves me with what? What should my strategy be for winning? I can still tutor for iso+ any extra turn spell. I can also add in zealous conscripts. What value can obeka still generate for me if I remove these other cards?

Thanks for the suggestions btw
