Tawnos, Solemn Survivor + Sky Hussar + Krark-Clan Ironworks

Tawnos, Solemn Survivor

Sky Hussar

Krark-Clan Ironworks

How it works

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

This cunning loop revolves around Tawnos, Solemn Survivor using its ultimate-style ability to resurrect Sky Hussar as an artifact copy from your graveyard. Once that initial copy hits the battlefield, its entry trigger untaps Tawnos and any other creatures you control, allowing you to pay {2} to endlessly duplicate the Hussar token with Tawnos's first ability. The engine is fueled and sustained by Krark-Clan Ironworks, which readily converts your surplus Sky Hussar tokens into the colorless mana needed to keep repeating the process while generating an infinite storm of artifact sacrifices and enters-the-battlefield triggers.
