introducing XYZ rn would complicate the game and frustrate many players, many agree that synchro era is when the game was at its best. They still have so much to milk from fusions and synchros. and the only D heros left to introduce is dreadmaster and dragoon
You forgot dystopia, dusktopia, dominance, defender, dynatag, disk commander, dread servant, dunker, drawhand and the spell and trap support like d-shield and clock tower prison.
