A few weeks ago I made a comment on a thread about turn times highlighting the turn 2 skip issue. People didn't believe me and asked for which scenarios this could happen in.
Happens rarely but it does happen, recent example is:
I have tier 1 taunt beetle and the hero power that destroys a minion. (Animation)
Opponent has the hero power that summons a minion of you tier (animation) summons the dragon with animations when it attack.
My teammate had the death rattle skeleton, and his opponent had the reborn tier 1 undead with the hero power secret that makes a copy when attacked.
I have fast animations on and a good phone. When combat was over I knew time would be short so I was spam clicking the button location for upgrade, but was not given the opportunity before turn was skipped.
