Hidetsugu and Kairi + Clone Legion + Mnemonic Wall

Hidetsugu and Kairi

Clone Legion

Mnemonic Wall

How it works

1. Cast Clone Legion by paying 7, causing you to create a token copy of Hidetsugu and Kairi and Mnemonic Wall.
2. Put the token Hidetsugu and Kairi into your graveyard due to the legend rule.
3. The Hidetsugu and Kairi token's first and second abilities trigger, as well as Mnemonic Wall.
4. Resolve the Mnemonic Wall trigger, returning Clone Legion from your graveyard to your hand.
5. Resolve the first Hidetsugu and Kairi trigger, causing you to draw three cards and then put Clone Legion and another card on top of your library, ensuring Clone Legion is on top.
6. Resolve the second Hidetsugu and Kairi trigger, exiling Clone Legion from the top of your library, then causing an opponent to lose 9 life and allowing you to cast Clone Legion from exile without paying its mana cost.
7. Resolve Clone Legion, causing you to create a token copy of Hidetsugu and Kairi and Mnemonic Wall.
8. Repeat from step 2.

This mesmerizing loop transforms a single cast of Clone Legion into an unstoppable engine of destruction by leveraging the legendary rule. When Clone Legion enters the battlefield to copy both Hidetsugu and Kairi and Mnemonic Wall, the resulting state immediately sends the legendary copy of Hidetsugu and Kairi to the graveyard, triggering its lethal death ability alongside Mnemonic Wall's helpful retrieval of Clone Legion. As Hidetsugu and Kairi sets up the top of your library for the impending explosion, the massive mana value of Clone Legion ensures that your opponent loses life in devastating chunks while you cast it for free over and over again.
