If you play Yu-Gi-Oh! and you don't play this card then you are a noob. I try my best not to say that, but it had to be said. The only way you aren't a noob if you don't run this is if the deck you are using is so broken that there is no need for it, and even at that I would still jump on it. MST is one of the best 1-1's we have.
