Origin Spellbomb + Salvaging Station + Krark-Clan Ironworks

Origin Spellbomb

Salvaging Station

Krark-Clan Ironworks

How it works

1. Activate Origin Spellbomb by paying 1, tapping and sacrificing it, creating a 1/1 Myr artifact creature token.
2. Origin Spellbomb leaves the battlefield; choose not to pay for its trigger to draw a card.
3. Activate Krark-Clan Ironworks by sacrificing the Myr, adding CC.
4. The Myr dies, triggering Salvaging Station, untapping Salvaging Station.
5. Activate Salvaging Station by tapping it, returning Origin Spellbomb from your graveyard to the battlefield.
6. Repeat.
