Thwarting Thassa's Oracle

In a game last night I was able to stop a Demonic Consultation/Thassa's Oracle combo win using Quandrix Command's humble fourth mode to put three cards back into their library with the Oracle ability on the stack. The Oracle player had no other blue devotion, so with three cards in library as the Oracle ability resolved, they did not win and ended up scooping instead. Immensely satisfying. This was (supposedly) a mid power game.

Do you have any good stories of stopping Thassa's Oracle or other combo wins?
