Basically, a high stakes game where if the oracle’s answers conflict, we both die.
The one who decides not to play the game will be the fake oracle.
The idea is trading off the real oracle (me) for a soulsnatcher, since I don’t know who in their right mind will try to claim to be an oracle if the person is innocent. One of us oracles is a soulsnatcher.
We kill BOTH ORACLES.
