Yenna, Redtooth Regent + Ashnod's Altar + Secret Arcade // Dusty Parlor + Sparring Mummy

Yenna, Redtooth Regent

Ashnod's Altar

Secret Arcade // Dusty Parlor

Sparring Mummy

How it works

1. Activate Yenna by paying 2 and tapping it, creating a token copy of Sparring Mummy.
2. When the Sparring Mummy token enters, it triggers, untapping Yenna.
3. Activate Ashnod's Altar by sacrificing the Sparring Mummy token, adding CC.
4. Repeat.

This clever loop turns Yenna, Redtooth Regent into an endless clone factory by taking advantage of Secret Arcade // Dusty Parlor, which cleverly turns your nonland permanents and permanent spells into enchantments so that Sparring Mummy counts as a valid copy target. With the Mummy reclassified as an enchantment, Yenna can tap to churn out a token copy of it, and the token's own entry trigger untaps Yenna in response to the hustle. You can then feed the token straight into Ashnod's Altar to generate the mana needed to fuel Yenna's ability all over again, netting infinite sacrifices and entry triggers along the way.
