Legendary creatures you control get +X/+X, where X is the number of legendary creatures you control.
Whenever you cast a legendary spell from your hand, exile cards from the top of your library until you exile a legendary nonland card with lesser mana value. You may cast that card without paying its mana cost. Put the rest on the bottom of your library in a random order.
Flood the board with legendary creatures, using Jodah's cascade-like ability to chain free legends off every legendary spell you cast. The anthem effect grows your whole team explosively as the legend count climbs, turning a wide board into a lethal alpha strike. Curve out with low-cost legends early, then cast bigger ones to cascade into a snowball of free spells.
Massive card advantage by casting free legends off every legendary spell from hand
Scaling anthem makes even small legends into huge threats quickly
Five-color identity allows the best legendaries and ramp/fixing in the format
Snowballs hard once stabilized, generating overwhelming board presence
Heavily reliant on the commander; struggles after repeated removal and tax
Vulnerable to board wipes that erase your wide legendary army
Trigger only chains off legendary spells cast from hand, not tokens or copies
Five-color mana base requires significant fixing investment
Lacks built-in protection or evasion without dedicated support
Draws a card every time you cast a legendary spell, refilling your hand alongside Jodah's value.
Tighten the curve with cheap, impactful legends so Jodah's cascade reliably hits and chains, and add fast mana like Sol Ring, Arcane Signet, and Jeweled Lotus to deploy him early. Improve fixing with original duals, fetches, and Triomes, then add protection (Lightning Greaves, Heroic Intervention) plus tutors like Captain Sisay and Eladamri's Call. Top-end finishers such as Jetmir or Craterhoof convert the wide board into reliable one-shot kills.
