Archaeomancer + Mystic Reflection + Time Warp + Sram's Expertise

Archaeomancer

Mystic Reflection

Time Warp

Sram's Expertise

How it works

1. Cast Time Warp 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, Time Warp, and Sram's Expertise to your hand.
5. Repeat.

This clever loop turns the token-creation of Sram's Expertise into a devastating engine for infinite turns by using Mystic Reflection to radically rewrite history. As your three Servos enter the battlefield, Mystic Reflection forces them to arrive instead as exact copies of Archaeomancer. This triggers all three Archaeomancers simultaneously, allowing you to harvest Time Warp, Mystic Reflection, and Sram's Expertise right back out of your graveyard and back into your hand. With Sram's Expertise also granting a free spell cast for anything costing mana value 3 or less, you have all the fuel necessary to cast Mystic Reflection anew, take all the time in the world with endless extra turns, and lock the game down completely.
