Skarbrands owner drops to 0 hp first. I shouldn't lose those games.
Example, card does 2 damage to skarbrand to do 5 damage to me.
5.1.4: The exception to the above is if a player is reduced to 0
health as a result of a card they played or Heroic Act they
used (even if it was just responsible for triggering an effect
that then reduced them to 0 health). In this case, that
player’s card is fully played out, then they are removed
5.1.5: If both players are reduced to 0 health during the same
action being played out; the player whose turn it is wins
That's dumb. At least it's not a big I guess.
I think it's done to prevent a draw happening in the game. There's also an achievement to win a game at 0 health!
