“Koa’ki Meiru Powerhand” only negates a monster’s effect while they are battling. This means that it only negates effects that activate on the field, or are continuous effects while on the field.

If “Koa’ki Meiru Powerhand” is destroyed by battle, its effect stops working from that point. Example: if “Koa’ki Meiru Powerhand” battles “Divine Knight Ishzark,” the effect of “Koa’ki Meiru Powerhand{{Spanremoved from play by the effect of “Divine Knight Ishzark.”
The effect negation ability of “Koa’ki Meiru Powerhand” begins when an attack target is declared. If “Koa’ki Meiru Powerhand” declares an attack on “Cyber Valley,” and the controller of “Cyber Valley{{Spanremoves it from play, “Cyber Valley{{Spanremoved from play but the controller will not draw a card, and the Battle Phase will not end, because the effect was activated on the field and is negated by “Koa’ki Meiru Powerhand.” (Also, since the number of potential attack targets has changed in this case, a replay will occur.)
OCG Rulings
The effect of "Koa'ki Meiru Powerhand" will only negate effects which activate on the field, or Continuous Effects which are applied for as long as the monster remains on the field. It cannot negate effects which activate in the Graveyard, like the effect of "Sangan".: Please explain the effect of "Koa'ki Meiru Powerhand" which negates the effects of LIGHT and DARK monsters.
If "Koa'ki Meiru Powerhand" battles with "Winged Kuriboh LV10" and "Winged Kuriboh LV10" activates its effect, then the effect will still be negated because it activated on the field, even though "Winged Kuriboh LV10" is no longer face-up on the field.
If "Koa'ki Meiru Powerhand" is destroyed by battle, then from damage calculation - when "Koa'ki Meiru Powerhand" is considered destroyed by battle - onward, it can no longer negate effects.
