• “Koa’ki Meiru Doom” will negate effects that activate outside of the field (such as the Graveyard or Removed Zone [sic]), as long as it is during the Main Phase.

• The effect of “Koa’ki Meiru Doom” is a Continuous Effect.

OCG Rulings

• The effect of "Koa'ki Meiru Doom" only negates effects which activate and start a Chain. It does not negate Continuous Effects, like that of "Jinzo".

• The effect of "Koa'ki Meiru Doom" will negate all effects of LIGHT and DARK monsters that activate during the Main Phase, even if the effect is not activated on the field. It will negate effects that activate in the hand and Graveyard, and it will negate effects that activate when the monster is removed from play.

Mentions in Other Rulings

• Iron Core of Koa'ki Meiru: While “Macro Cosmos” is active, you cannot send “Iron Core of Koa’ki Meiru” to the Graveyard to pay the cost of keeping your “Koa’ki Meiru” monster on the field. So you must either pay the reveal cost, or destroy the monster.
