Terra, Magical Adept // Esper Terra + The Apprentice's Folly

Steps

1. Activate Terra, Magical Adept by paying {4}{R}{G} and tapping it, exiling it and returning it to the battlefield as Esper Terra and with a lore counter on it.
2. Esper Terra triggers, creating a copy of The Apprentice's Folly and causing it to enter the battlefield with a lore counter on it.
3. The Apprentice's Folly's first ability triggers, creating a token copy of Esper Terra that isn't legendary with a lore counter on it.
4. When the Esper Terra token enters the battlefield, its first chapter ability triggers, creating a token copy of itself with haste and four lore counters on it.
5. When the Esper Terra token enters the battlefield, its first, second, third and fourth chapter abilities trigger.
6. Resolve the first and second trigger, creating token copies of any nonlegendary enchantment you control.
7. Resolve the fourth trigger, causing you to add {W}{W}{U}{U}{B}{B}{R}{R}{G}{G} and exile the Esper Terra token.
8. Resolve the third trigger, creating a token copy of the Esper Terra token created in step 4 with haste and four lore counters on it.
9. Repeat from step 5.
