Forum:Skill Drain vs. Grave of the Super Ancient Organism

Skill Drain: Pay 1000 Life Points. The effects of all face-up Effect Monsters are negated.

Grave of the Super Ancient Organism: All face-up Level 6 or higher Special Summoned monsters on the field cannot declare an attack or activate their effects.

Is there a difference?? Gomer1234 (talk • contribs) 02:43, August 4, 2011 (UTC)
