How it works
Status: Limited in the TCG (Sept 21, 2026 list), so you can run 1 copy.
Rivalry of Warlords is a Continuous Trap. While it’s face-up, each player can only control 1 Type of monster, and sends all other face-up monsters they control to the GY.
Rulings in plain English
Activation: Not in the Damage Step. The effect itself isn’t activated; it applies while the card is face-up.
When it starts applying: A player with face-up monsters of 2+ Types sends monsters to the GY until they control only 1 Type.
Summoning: You can’t Normal Summon, Flip Summon, or face-up Special Summon a monster of a different Type from your face-up monsters. You also can’t summon a different Type to your opponent’s field than their face-up monsters. Setting and face-down Special Summons are still fine.
Flips and control changes: If these create a second Type, the monster that newly became face-up there is sent to the GY, with no chain. If several are flipped or summoned at once, some or all of those are sent.
Not affected by the Trap: Monsters sent this way are chosen by the player and aren’t treated as sent by a Trap effect, so Trap immunity doesn’t stop it.
