Card Rules: Rulings powered by The Netrep API. [Re: Blade Knight] If 'Blade Knight' destroys a Flip Effect Monster like 'Slate Warrior' , even that monster's non-Flip effects are negated. So in this case 'Slate Warrior' does not reduce the ATK and DEF of the 'Blade Knight' that destroyed it because 'Blade Knight' negates its effect. [Re: Dark Ruler Ha Des] Monster effects that activate after damage calculation will be negated if your Fiend-Type monster destroys the opposing Effect Monster. Examples include 'D.D. Warrior Lady' 'Thousand Needles' 'Slate Warrior' 'Ryu Kokki' and 'Wall of Illusion'. [Re: Gorgon's Eye] 'Gorgon's Eye' cannot negate the effect of 'Sangan' 'Witch of the Black Forest' or 'Sinister Serpent' because they activate in the Graveyard. If a Defense Position 'Slate Warrior' is attacked and destroyed the effect of 'Slate Warrior' that lowers ATK and DEF is applied because it activates in the Graveyard. [Re: Grave Protector] If 'Grave Protector' is on the field the effect of 'Slate Warrior' that reduces the ATK and DEF of the monster that destroys 'Slate Warrior' is still applied even though 'Slate Warrior' is shuffled back into the Deck instead of being sent to the Graveyard. The timing of 'Slate Warrior's' effect is still at the end of the Damage Step (when monsters are normally sent to the Graveyard after battle). [Re: Skill Drain] When a monster's ATK or DEF are changed by its own effect like 'Slate Warrior' or 'Berserk Dragon' and 'Skill Drain' is activated that monster's effect is negated and the ATK/DEF are returned to normal. Even if 'Skill Drain' is then destroyed the old adjustment to ATK/DEF does not come back. Any bonuses or penalties are lost when 'Skill Drain' effect is applied and you have to start over from the beginning.
