This clever loop weaponizes Inverter of Truth’s dramatic entry trigger, which exiles your library and sweeps your graveyard back into your deck. Because those creature cards are technically leaving your graveyard to be shuffled away, Syr Konrad, the Grim sees every single one depart and triggers a massive wave of damage to your opponents. To ensure this blast of damage immediately translates to a win through infect rather than regular life totals, Glistening Oil is enchanted onto Syr Konrad, transforming that damage into lethal poison counters that close out the game on the spot.
