The 4 combo pieces

• Isochron Scepter
• Mechanized Production
• Ugin's Nexus
• Vision Charm

How to execute it

1. At the beginning of your upkeep, Mechanized Production triggers, creating a token copy of Ugin's Nexus.
2. Put the Ugin's Nexus token into your graveyard due to the legend rule.
3. The Ugin's Nexus token is exiled instead of being put into your graveyard, causing you to take an extra turn after this one.
4. Activate Isochron Scepter by paying {2} and tapping it, casting a copy of Vision Charm without paying its mana cost.
5. Resolve the copy of Vision Charm, causing Ugin's Nexus to phase out until your next untap step.
6. Move to your next turn, causing Ugin's Nexus to phase in during your untap step.
7. Repeat.
