Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight + Yahenni, Undying Partisan + Virtuous Variant

Eirdu, Carrier of Dawn // Isilu, Carrier of Twilight

Yahenni, Undying Partisan

Virtuous Variant

How it works

1. Activate Yahenni by sacrificing Virtuous Variant.
2. When Virtuous Variant dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. When Virtuous Variant enters, it triggers, putting a +1/+1 counter on it.
4. Resolve the Yahenni ability.
5. Repeat.
