Yurlok of Scorch Thrash + Staff of Domination + Nyxbloom Ancient

Yurlok of Scorch Thrash

Staff of Domination

Nyxbloom Ancient

How it works

1. Activate Yurlok of Scorch Thrash by paying 1 and tapping it, causing each player to add .
2. Activate Staff of Domination's third ability by paying 3 and tapping it, untapping Yurlok of Scorch Thrash.
3. Activate Staff of Domination's first ability by paying 1, untapping it.
4. Repeat an arbitrarily large number of times.
5. Once each player has infinite mana, use any of Staff of Domination's abilities, along with its first ability, to empty your mana pool.
6. Move to the next step or phase, causing each player to lose life equal to the mana they lost.

This clever loop relies on the mana-tripling power of Nyxbloom Ancient, which turns Yurlok of Scorch Thrash's tapped ability from a modest color-pie gift into an explosive nine-mana windfall for every single player. By channeling a portion of that generated bounty into Staff of Domination, you can repeatedly untap Yurlok of Scorch Thrash and the artifact itself to cycle through an arbitrarily large quantity of black, red, and green mana. Because Yurlok of Scorch Thrash's static ability transforms any leftover unspent mana into direct life loss when phases change, you can easily filter away your own surplus with Staff of Domination's activated abilities while letting your opponents drown in lethal, unspent energy.
