6 Tellarknights are a Phenomenal XYZ Strategy Best Card: Stellarknight Triverr In the early 2010s, Tellarknight decks were some of the best in the game
One useful tip I can give you is that it's better with "Alviss of the Nordic Alfar" effect to discard from deck the most useless Nordic monsters (most of the times the level 4 and some level 3 beast-type cards)
