Time Sieve + Mycosynth Lattice + Rionya, Fire Dancer + Evangel of Heliod

Time Sieve

Mycosynth Lattice

Rionya, Fire Dancer

Evangel of Heliod

How it works

1. At the beginning of your combat phase, Rionya triggers, creating at least one token copy of Evangel of Heliod with haste.
2. When the Evangel of Heliod token enters the battlefield, it triggers, creating at least four 1/1 Soldier creature tokens.
3. Activate Time Sieve by tapping it, sacrificing the Evangel of Heliod token and the Soldier tokens, causing you to take an extra turn after this one.
4. Repeat each turn.

This ingenious loop twists the laws of the battlefield by using Mycosynth Lattice to turn your entire board into artifacts, making every single permanent ready and willing fodder for Time Sieve. As combat begins, Rionya, Fire Dancer whips up a hasty copy of Evangel of Heliod, whose devotion-fueled entrance floods the field with white Soldier tokens. Because Mycosynth Lattice has rendered those newly arrived Soldiers and token copies into full-fledged artifacts, you can immediately feed them—along with the Evangel itself—to Time Sieve's activation cost, cashing them in for an extra turn. By repeating this process on each subsequent combat phase, you secure an infinite sequence of extra turns to completely lock down the game.
