Princess Yue + Wormfang Turtle + Dack's Duplicate

Princess Yue

Wormfang Turtle

Dack's Duplicate

How it works

1. Cast Dack's Duplicate by paying its mana cost. Choose to have it enter as a copy of Princess Yue.
2. Put Dack's Duplicate into your graveyard due to the legend rule.
3. When Dack's Duplicate dies, it triggers, returning it from your graveyard to the battlefield as a land named Moon. Choose to have it enter as a copy of Wormfang Turtle, gaining its abilities.
4. When Dack's Duplicate enters, its first ability triggers, exiling it.
5. When Dack's Duplicate leaves the battlefield, its second ability triggers, returning Dack's Duplicate from exile to the battlefield. Choose to have it enter as a copy of Princess Yue.
6. Repeat from step 2.
