Princess Yue + Wormfang Turtle + Omni-Changeling

Princess Yue

Wormfang Turtle

Omni-Changeling

How it works

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