How it works

1. At the beginning of your end step, Ziatora triggers, causing you to sacrifice another creature with power one or greater.
2. Ziatora triggers, holding priority, activate Strionic Resonator by paying 2 and tapping it, copying Ziatora's ability.
3. Resolve the copy of Ziatora's ability, dealing damage equal to the sacrificed creature's power to any target and creating three Treasure tokens.
4. Activate Clock of Omens by tapping two Treasure tokens, untapping Strionic Resonator.
5. Activate Krark-Clan Ironworks by sacrificing a Treasure token, adding CC.
6. Activate Strionic Resonator by paying 2 and tapping it, copying Ziatora's ability.
7. Repeat from step 3.
