Did you ever see a Clone Priest that cast Obliterate with Malygos or Velen up and wondered why the spell damage buffs had no impact? If so, you can check out my article for TRS that explains everything here https://teamrankstar.com/whats-up-with-obliterate-and-spell-damage/ …
Yeah, that Obliterate interaction is very strange. As I said in the article, on-draw effects aren't impacted by spell damage, so the Scroll of Wonders shouldn't be buffed. Thanks for bringing this up, it reminded me of some other cards that I'm going to add to the article now!
