Time Sieve | Encroaching Mycosynth | Delina, Wild Mage

(and one other card)

All permanents on the battlefield.
Delina does not have summoning sickness and cannot be blocked and killed by an opponent.

Declare
Delina as an attacker.
Delina 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.
