How it works

2. Activate Grenzo by paying 2, putting Threefold Thunderhulk into your graveyard from the bottom of your library, and then putting it onto the battlefield.
3. When Threefold Thunderhulk enters the battlefield, it triggers, creating three 1/1 Gnome artifact creature tokens.
4. Activate Krark-Clan Ironworks three times by sacrificing Threefold Thunderhulk and two Gnomes, adding six C.
5. Repeat.
