Princess Yue

Wormfang Turtle

How it works

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