Now, allow me to explain why that's bullshit.
The Crimson Dragon literally creates cards out of nothing and places them on top of Yusei's deck. What I'm getting at is it can pull an Anti-Divine Serpent out of its ass, give it to Yusei, and Yusei would wreck it.
Nobody goes anywhere. Quasar can still negate attacks, right? Also, let's be honest. As rarely as it happens, the Crimson Dragon will give Yusei a new, easy-to-summon Stardust card with an ability the same as the Wicked Avatar.
You obviously don't understand what FTK Quasar does.
And two, using Shooting Star Dragon's attack negation effect and/or Scrap Iron and/or Effect Veiler to stall him out for the former two and just utterly troll him for the latter.
