Effect
If you control both LIGHT and DARK monster(s): You can target 1 of your banished LIGHT or DARK Warrior-Type monsters; add it to your hand. You can only activate 1 "Chaos Seed" per turn.
To activate "Chaos Seed", you must have at least one face-up LIGHT monster and at least one face-up DARK monster on your side of the field. (However, if "Black Luster Soldier - Envoy of the Evening Twilight" is present, you can activate "Chaos Seed" even if no other monsters are present.)
Activate by targeting 1 of your banished LIGHT Warrior-Type monsters, or 1 of your banished DARK Warrior-Type monsters.
You can also target a Fusion, Synchro, or Xyz Monster with the effect of "Chaos Seed". (In that case, it returns to the Extra Deck instead of being added to your hand.)
Even if you no longer have a LIGHT monster, a DARK monster, or both on your side of the field when the effect resolves, the effect is applied normally.
