Replays shared by T0nomi here show that Warabi only played 9 so I most likely messed up my logs. My logs show I played Warabi twice in lenshu, when in fact (according to the replays), I only played him once.

Instead, I played Enchantress and won. I lost my lenshu against Warabi. And this "Warabi wins" in a Fire vs Enchantress match is a typo, I won that game.

Hope this clears things up.
