I don't think any of Yuma's shitty friends have used enough cards on screen to have a full deck, even if you assume 3 of each cards and that none of them are anime exclusive
At least going off Yu-gi-oh wikia's card list for each of them
It was a joke lol
Anna has a fully operational deck, but I don't think she counts as a shitty friend. She was funny.
But yes, they don't have enough cards, makes me wonder why those characters even exist.
EDIT: As for ZEXAL, I also watched all of it. And its terrible but you can't stop watching, like a trainwreck.
The part that angers me the most is that its full of Cool characters like Shark, Kaito, IV, Rio,Dextra and of course Vector. All of them with awesome deck themes and some interesting motives at first
And every single one of those characters is ruined spectacularly at some point.
That's what makes the series one of the worst, as soon as it starts to show promise it jumps into a pile of Crap just to be safe.
