Good weapon against the Scandinavian?

Hello everyone I was wondering if you have any recommendations against the Scandinavian Defense currently I just take the pawn but I’m looking to see if there are other ways I can play against it.

I sometimes play the tennison gambit against it but after a certain level it stops working

I literally just do this:

2.Nc3 is what I prefer over 3.Nc3

Against a Viking? A gun. 

Jokes aside, exd5 is probably the best response.

Main lines are very good against it.

I've been transposing to the Blackmar-Diemer to avoid Scandinavian lines because for some reason I just have no clue how to attack it as white. 

In my experience, 1.c4 is a good refutation as you keep both center pawns. Naturally, it's assuming your opponent will play the Scandi.
