Time Sieve | Mycosynth Lattice | Rionya, Fire Dancer

(and one other card)

At the beginning of your combat phase,
Rionya triggers, creating at least one token copy of
Evangel of Heliod with haste.
When the
Evangel of Heliod token enters the battlefield, it triggers, creating at least four 1/1 Soldier creature tokens.
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.
Repeat each turn.
