Muldrotha, the Gravetide + Ruthless Technomancer + Kaya's Ghostform + Yahenni, Undying Partisan

Muldrotha, the Gravetide

Ruthless Technomancer

Kaya's Ghostform

Yahenni, Undying Partisan

How it works

1. Cast Ruthless Technomancer either from your hand or graveyard by paying 3.
2. When Ruthless Technomancer enters the battlefield, it triggers, causing you to sacrifice Muldrotha and create six Treasure artifact tokens.
3. When Muldrotha dies, Kaya's Ghostform triggers, returning Muldrotha from your graveyard to the battlefield.
4. Activate Yahenni by sacrificing Ruthless Technomancer, giving it indestructible until end of turn.
5. Activate five Treasure tokens by tapping and sacrificing them, adding 3.
6. Cast Kaya's Ghostform from your graveyard by paying , attaching it to Muldrotha.
7. Repeat.

This ingenious loop turns Muldrotha, the Gravetide into a perpetual engine by leveraging her own graveyard-playing ability to continuously recast her protectors. When Ruthless Technomancer enters the battlefield, it sacrifices Muldrotha to generate a flood of Treasure tokens, which then provide the mana needed to recast Kaya's Ghostform from the graveyard and fuel the Technomancer's return. Meanwhile, Kaya's Ghostform ensures Muldrotha instantly bounces right back whenever she falls, and Yahenni, Undying Partisan stands ready to sacrifice the Technomancer on command while keeping the loop safe.
