Tawnos, Solemn Survivor + Hyrax Tower Scout + Krark-Clan Ironworks

Tawnos, Solemn Survivor

Hyrax Tower Scout

Krark-Clan Ironworks

How it works

1. Activate Tawnos's second ability by paying 1, tapping it and sacrificing two artifact tokens, exiling Hyrax Tower Scout from your graveyard and creating a token copy of it that is an artifact in addition to its other types.
2. When the Hyrax Tower Scout token enters, it triggers, untapping Tawnos.
3. Activate Tawnos's first ability by paying 2 and tapping it, creating a copy of the Hyrax Tower Scout token and causing you to mill two cards.
4. When the Hyrax Tower Scout token enters, it triggers, untapping Tawnos.
5. Activate Krark-Clan Ironworks by sacrificing a Hyrax Tower Scout token, adding CC.
6. Repeat from step 3.

This intricate loop turns Tawnos, Solemn Survivor into an engine of continuous recreation by leveraging the mana-generating engine of Krark-Clan Ironworks. With Hyrax Tower Scout exiled and waiting in your graveyard, Tawnos can use its heavy activation cost to birth the Scout anew as an artifact creature, whose entry trigger immediately untaps Tawnos for more work. From there, Tawnos's first ability can repeatedly copy the artifact Scout token for a mere two mana, continually untapping itself while Krark-Clan Ironworks feeds on the excess tokens to generate the colorless mana needed to keep the cycle spinning.
