Rootha, Mercurial Artist + Sneak Attack + Channel the Suns

Rootha, Mercurial Artist

Sneak Attack

Channel the Suns

How it works

1. Cast Channel the Suns by paying 3.
2. Holding priority, activate Rootha by paying 2 and returning it from the battlefield to your hand, copying Channel the Suns.
3. Resolve the copy of Channel the Suns, adding .
4. Activate Sneak Attack by paying , putting Rootha from your hand onto the battlefield.
5. Repeat from step 2.

This clever loop uses Rootha, Mercurial Artist as a self-returning engine to continuously copy Channel the Suns. By sacrificing mana to pay for Rootha's activation—which bounces her back to your hand while duplicating the spell—you generate a net surplus of mana each iteration. Sneak Attack then provides the crucial missing link, letting you cheat Rootha right back onto the battlefield from your hand using a fraction of your newly minted mana, setting the stage to repeat the entire process indefinitely.
