Why? because he has a magic "Dues Ex Machina" card pulling ability.
Pulling some card that Lelouche probably didn't even know existed since there is like a 70% chance yugi is making up the very specific rules as he goes along anyway.
"This card allows me to destroy all your monsters and deal you 15,000 life points damage... so long as i' am facing somone in a purple outfit!"
"Ah... but I have Spell Jammer."
"This card's effect can't be negated.... uh. Also you have to give me 5 dollars. Yeah.... 5 dollars.
