Just finished my last played game in Arena and lost due to this issue:
Cast Shudderblock. The following turn, cast an activated Baba Naga directed at opponent’s face. The graphic triggered 3 times, but the end result was 0 damage.
Game was between me player #15425 and against player #1836 in arena.
It has never changed, it’s how the card has been announced and released, with an explicit entire sentence that people keep on missing and report as a bug instead of reading the card to check how it works
