Terra, Magical Adept // Esper Terra + Yenna, Redtooth Regent

Terra, Magical Adept // Esper Terra

Yenna, Redtooth Regent

How it works

1. Activate Yenna by paying 2 and tapping it, creating a nonlegendary token copy of Esper Terra.
2. 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.
3. When the new Esper Terra token enters the battlefield, its first, second, third and fourth chapter abilities trigger.
4. Resolve the first and second trigger, creating token copies of any nonlegendary enchantment you control.
5. Resolve the fourth trigger, causing you to add and exile the Esper Terra token.
6. Resolve the third trigger, creating a token copy of the Esper Terra token created in step 1 with haste and four lore counters on it.
7. Repeat from step 3.

By leveraging Yenna, Redtooth Regent to create a nonlegendary token copy of the transformed Esper Terra, you kick off a dazzling chain reaction of copying and mana generation. Because Esper Terra's chapters immediately trigger upon entering the battlefield—simultaneously adding a massive burst of all five colors of mana and spawning yet another copy of the Saga—the loop perpetually feeds itself. This creates an endless cycle of enters-the-battlefield triggers, haste-granting tokens, and explosive mana that can quickly overwhelm your opponents.
