Yenna, Redtooth Regent + Ashnod's Altar + Jump Scare + Hyrax Tower Scout

Yenna, Redtooth Regent

Ashnod's Altar

Jump Scare

Hyrax Tower Scout

How it works

1. Cast Jump Scare by paying , targeting Hyrax Tower Scout.
2. Activate Yenna by paying 2 and tapping it, creating a token copy of Hyrax Tower Scout.
3. When the Hyrax Tower Scout token enters, it triggers, untapping Yenna.
4. Activate Ashnod's Altar by sacrificing the Hyrax Tower Scout token, adding CC.
5. Repeat from step 2.

This ingenious little loop turns a simple trick of identity into an endless engine, fueled by Yenna, Redtooth Regent's ability to replicate enchantments. By temporarily transforming Hyrax Tower Scout into a Horror enchantment creature using Jump Scare, you prime it to be copied directly off of Yenna's tap ability. Every time the resulting token copy hits the battlefield, its enters-the-battlefield trigger untaps Yenna, while Ashnod's Altar stands ready to feed that same token to the graveyard for colorless mana—leaving Yenna ready to spin the wheel all over again.
