Archaeomancer + Mystic Reflection + Capture of Jingzhou + Sram's Expertise

Archaeomancer

Mystic Reflection

Capture of Jingzhou

Sram's Expertise

How it works

1. Cast Capture of Jingzhou by paying 3, granting you an extra turn after this one.
2. Cast Mystic Reflection by paying 1, causing the next creatures or planeswalkers to enter the battlefield this turn to enter as copies of Archaeomancer.
3. Cast Sram's Expertise by paying 2, creating three token copies of Archaeomancer and allowing you to cast a card with mana value 3 or less from your hand without paying its mana cost.
4. Each of the Archaeomancer's ETBs trigger, returning Mystic Reflection, Capture of Jingzhou, and Sram's Expertise to your hand.
5. Repeat.
