Rootha, Mercurial Artist + Hellkite Courser + Ashnod's Altar + Saheeli's Artistry

Rootha, Mercurial Artist

Hellkite Courser

Ashnod's Altar

Saheeli's Artistry

How it works

1. Cast Saheeli's Artistry by paying 4, targeting Hellkite Courser.
2. Holding priority, activate Rootha by paying 2 and returning it to your hand, targeting Saheeli's Artistry.
3. Choose to have Rootha returned to the command zone instead of your hand.
4. Resolve the Rootha ability, copying Saheeli's Artistry, targeting Hellkite Courser.
5. Resolve the copy of Saheeli's Artistry, creating a token copy of Hellkite Courser that is also an artifact.
6. The Hellkite Courser token enters the battlefield, putting Rootha from the command zone onto the battlefield.
7. Activate Ashnod's Altar by sacrificing the Hellkite Courser token, adding CC.
8. Repeat from step 2.
9. Optionally, you may choose both modes of Saheeli's Artistry to create infinite tokens of any artifact(s) on the battlefield.
