Princess Yue + Wormfang Turtle + Phyrexian Metamorph

Princess Yue

Wormfang Turtle

Phyrexian Metamorph

How it works

1. Cast Phyrexian Metamorph by paying its mana cost. Choose to have it enter as a copy of Princess Yue.
2. Put Phyrexian Metamorph into your graveyard due to the legend rule.
3. When Phyrexian Metamorph 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 Phyrexian Metamorph enters, its first ability triggers, exiling it.
5. When Phyrexian Metamorph leaves the battlefield, its second ability triggers, returning Phyrexian Metamorph from exile to the battlefield. Choose to have it enter as a copy of Princess Yue.
6. Repeat from step 2.
