YGO has like 70 episodes of filler. Two of the arcs, being >>10894636
, are both fillers. Regardless to say, the manga is a LOT more fast paced.
The difference with YGO fillers is that it's extremely good, and absolutely worth watching. I fucking bawww'd at the end of the Noah Kaiba arc.
Also, I think Dungeon Dice Monsters was canon, though im not sure.
