Tawnos, Solemn Survivor + Great Oak Guardian + Krark-Clan Ironworks

Tawnos, Solemn Survivor

Great Oak Guardian

Krark-Clan Ironworks

How it works

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

This clever loop turns the graveyard into a foundry of ever-multiplying giants, anchored by Tawnos, Solemn Survivor and fueled by the mana-generating engine of Krark-Clan Ironworks. By using Tawnos's sorcery-speed ability to materialize an artifact copy of Great Oak Guardian from the graveyard, every subsequent iteration triggers the Guardian's entry ability to untap your board and pump your creatures. Tawnos's first ability then steps in to endlessly duplicate that very same token, while Krark-Clan Ironworks stands ready to sacrifice the excess copies for raw colorless mana to sustain the loop.
