Danitha, Benalia's Hope + Minion's Return + Yahenni, Undying Partisan

Danitha, Benalia's Hope

Minion's Return

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Danitha.
2. When Danitha dies, Minion's Return triggers, returning Danitha from your graveyard to the battlefield tapped.
3. When Danitha enters the battlefield, it triggers, returning Minion's Return from your graveyard to the battlefield attached to Danitha.
4. Resolve the Yahenni ability.
5. Repeat.
