...First guy to tell me D/D isn't 90% skill gets a slap to the face ._.

Sure, Luck is a factor in ANY game that isn't named chess, which goes doubly for card and dice games. Just because luck is a factor, though, doesn't mean it's not a skill game. Not so much anymore, but in the past you could climb to Legendary in Hearthstone with nothing but base cards, and Hearthstone is considered one of the most luck-based card games on the planet.

YGO is a skill game, it just also has the problem of being a card game.
