The goal is to get out synchrs (or exceeds). Withe super-nimble you can summon Tanngnjostre or Tanngrisnir. With Tanngnjostre you can sommon some nordic monster from your deck to synchro summon or exceed summon. While Tanngrisnir is usefull if your oponent destroys him you can special summon two tokens. If you have Gleipnir you can get a Guldafaxe to your hand(if you do not have one in your hand) and go for Thor.
To get some def (and mostly just for fun) or to get off some strong monster you can go for hane hane. You are also able to go for ryko an destroy smth. Gravekeeper engine is selfexplaining.
You also can play whatever y synchro or exceed you prefer, only Thor is the one which you should definitely play.
