"You're a third-rate Duelist with a fourth-rate Deck!" is a quote from the game Yuu-Gi-Ou Duel Links. See http://imgur.com/a/7TetN

Another quote is "You could never defeat a Duelist with talent!" See here.

In episode 136 of the anime "Battle for the Bronze, Part 2", Kaiba says something similar to both of these quotes (starting at 7:10):

Joey: "You stole my Legendary Sword! Agh! And my attack points!"
Kaiba: "That was a third-rate strategy, Wheeler! Just as I suspected. You could never defeat a Duelist with real talent."
