I have 3 strategies that need Nordic Lights
Thor: Play tanngrisnir or tanngnjostr face-down and save from destruction. Switch to atk and special summon guldfaxe (I thought it was pronounced Gold-fax-e) and summon other nordic beast and synchro
Loki: Play mara and synchro using alviss and ljosalf for Loki. Keep some nordics in gy in case of death.
Odin: Play valkyrie and send 2 traps to gy for tokens and synchro for Odin.
If you play all 3 (In that order) make sure to special summon jormungardr and fenrir (In defense) and keep gy loaded
