This wondrous alchemy hinges upon Mycosynth Lattice, whose passive gift turns every permanent on your battlefield into an artifact, paving the way for non-artifact creations to fuel Time Sieve. When you declare Delina, Wild Mage as an attacker, her triggered ability lets you roll a d20 to create a token copy of Avenger of Zendikar; if you roll a 15 or higher, you can even roll again to make more! That Avenger of Zendikar token floods your board with 0/1 Plant creature tokens via its entry trigger, providing the exact count of five artifacts needed to satisfy Time Sieve's activation cost. By sacrificing the Avenger of Zendikar token and its accompanying Plant tokens, Time Sieve grants you an extra turn, allowing you to repeat this dazzling cycle indefinitely and lock down the game.
