How it works

1. Activate Feldon by paying 2 and tapping it, creating a token copy of Slobad with haste that is an artifact in addition to its other types.
2. Activate the Slobad token by tapping it and sacrificing Spine of Ish Sah, adding seven that can only be spent to cast artifact spells or to activate abilities of artifacts.
3. Spine of Ish Sah leaves the battlefield, returning itself from your graveyard to your hand.
4. Cast Spine of Ish Sah by paying 7.
5. Traxos triggers, untapping itself.
6. Spine of Ish Sah enters the battlefield, destroying target permanent.
7. Activate Clock of Omens by tapping Traxos and Spine of Ish Sah, untapping the Slobad token.
8. Repeat from step 2.
