Rootha, Mercurial Artist

Hellkite Courser

Ashnod's Altar

Replication Technique

How it works

1. Cast Replication Technique by paying 4, targeting Hellkite Courser.
2. Holding priority, activate Rootha by paying 2 and returning it to your hand, targeting Replication Technique.
3. Choose to have Rootha returned to the command zone instead of your hand.
4. Resolve the Rootha ability, copying Replication Technique, targeting Hellkite Courser.
5. Resolve the copy of Replication Technique, creating a token copy of Hellkite Courser.
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.
