This Vintage combo achieves infinite mana by turning your creatures into powerhouses of blue production using Steward of the Harvest. Once Steward of the Harvest has exiled Tolarian Academy from your graveyard, it gains the land's ability to tap for blue mana based on your artifact count. Sword of the Paruns ties the whole engine together by providing the active untapping mechanism: you can tap the creature for a massive windfall of mana, then spend a portion of that energy via Sword of the Paruns's ability to untap it and repeat the cycle indefinitely.
