Forum:Prime material dragon help please

My opponnent has Widespread ruinn on the field and I have Prime Material Dragon only on my field.I declare a attack and he activates widespread ruin trying to destroy my dragon and I chain his effect discarding 1 card from my hand to negate Widespread ruin and prevent destruction of my dragon.He claims that I cannot do that because there is no text "including this card" in Prime material dragon effect.So please answer me these two questions?

Can Prime Material Dragon negate Widespread riun?

Can Prime Material prottect himself with his effect?
