Urza, Prince of Kroog + Radiant Lotus + The Enigma Jewel // Locus of Enlightenment + Frostcliff Siege

Urza, Prince of Kroog

Radiant Lotus

The Enigma Jewel // Locus of Enlightenment

Frostcliff Siege

How it works

1. Activate Urza by paying 6, targeting Radiant Lotus.
2. Locus of Enlightenment triggers, copying Urza's ability, targeting Radiant Lotus.
3. Resolve both Urza abilities, creating two token copies of Radiant Lotus that are 1/1 Soldier artifact creatures.
4. Activate a Radiant Lotus token by tapping it and sacrificing both Radiant Lotus tokens, targeting yourself.
5. Locus of Enlightenment triggers, copying the Radiant Lotus token's ability, targeting yourself.
6. Resolve both Radiant Lotus abilities, adding twelve mana of any color.
7. Repeat.

This ingenious loop hinges on The Enigma Jewel's transformed side, Locus of Enlightenment, which copies any non-mana activated ability you trigger—a property that turns Urza, Prince of Kroog's token-copying activation into a double-creation engine. By paying Urza's mana cost to target Radiant Lotus, Locus of Enlightenment doubles the effect to yield two token copies of the Lotus, which conveniently arrive with haste thanks to Frostcliff Siege's Temur mode. You then tap one of those new token copies and sacrifice both of them to Radiant Lotus's mana ability, a move that Locus of Enlightenment copies yet again to flood your mana pool with an overwhelming surge of colored mana.
