This explosive pairing turns your opponent's own board state against them by using Cavern-Hoard Dragon's triggered ability to flood your side of the table with Treasure tokens based on how many artifacts they control. Once those riches are generated, you simply feed five of those treasures to Time Sieve, cashing them in to take an extra turn after this one. Because the Dragon boasts flying, trample, and haste to reliably punch through for combat damage turn after turn, you can repeat this cycle to secure near-infinite turns and lock your opponents out of the game entirely.
