Yu-Gi-Oh began as a manga by Kazuo Takahashi in 1996 and became a long running anime about duelist Yugi Moto and the spirit Yami Yugi. A central idea in the series is trusting the heart of the cards before a crucial draw, a line repeated through duels and dubs around the world. The Portuguese version, shortened here to eu acredito, keeps that same hopeful declaration in a two second form that fans share as a reaction and meme sound.
