X, Yu☆Gi☆Oh! 5D's Recommendations
Dark Signers Arc is basically Yugioh meets X/1999 without Gorn. Elements of Dragon, Fate, and World Destruction plays the key in both shows. The only difference is that there are 5 Dragons in 5ds and 14 dragons in X but the opposing sides share a common goal: destroy the current world and reform a new one. In other words 10 participants: 5 signers vs 5 dark signers and 14 participants:7 dragons of heaven vs 7 dragons of earth. It is really thrilling and fast pacing in 5ds but at the same time shonen whereas X gets all the death tolls as the battle goes on.
