Hello!

For me, at the stage of the game. You can opt to get a ninja first but do plan well on what ninjas or team you will make. Pick one of the Position 1 ninja and one Support ninja for Position 2 and after that, go for power until you reach a certain point. It is up to you on how you will play this game, just like what UchihaShay said above, it will depend on you on what type of fun you will want to have.
