Forum:Prometheus, optinal number?

Prometheus, King of the Shadows

When you Normal Summon this card, remove from play any number of DARK monsters in your Graveyard. This card gains 400 ATK for each removed card, until the End Phase of this turn.

Anyone know whether "any number" refers to an optinal number or is just a therm used because you never know the number of monsters?

Example: There are 7 DARK monsters in your Graveyard. You summon Prometheus. Do you remove all 7 monster or are you able to choose the number so that you could only remove like 5 monsters and have 2 remain in your graveyards.

Anyone can help? thanks in advance. Nuin Maltice 13:03, 30 November 2008 (UTC)
