Suspicious interaction
After Divine Purge on Emry, play her down from exile. Opponent doesn't use wandering emperor to exile and passes to me, I use Emry to play Paradox from graveyard, then use last mana to cast an aether spellbomb, untap emry and some mana, use the spellbomb to bounce a token, then, upon using emry to target the spellbomb, my turn suddenly ends, emry is exiled and my opponent immediately does their turn... My opponent was tapped out, there's no spells in exile or graveyard, there's no effects, I had open mana and could have responded to anything, I wasn't roped.
I have no idea what happened at all. Either I'm completely missing multiple split second interactions and a turn ending effect that doesn't use a card, the game completely de-synced for half a turn and then re-synced without showing me what happened or my opponent somehow cheated.
