At 4.25pm during my second round of the Arena open strange thing happened.I had the "anthem" on the battlefield, which is boosting my creatures 1+1. I had Mild-Mannered Librarian non boosted on the battlefield. I blacked opponent 2/2 creature with Librarian and played Snakeskin Veil to get it 1+1 counter. My creature supposed to survive, but it traded in the combat.
Could you inspect this situation or give me any valid explanation for this "issue"? I finished the run 3/3, but if there wouldn't be this error I believe I could do better. Please check and find the correct solution for this situation, because apparently the arena is bugged as hell. I play Arena more then 5 years and MTG more then 15 year. This situation in past weeks in arena is horrible. Maybe because there is a lot of new sets coming at once, but you should definitely fix it somehow.
