After the release of Primal Origin a lot of players aren,t playing Mystical Space Typhoon(MST) anymore or they are just playing one, But why do they no longer play MST? In Primal Origin the Artifact Archetype was released in the TCG. Whenever an Artifact card is destroyed in the spell or trap card zone on their opponents turn they are special summoned and they will get another effect. The main Artifact monster that you have to worry about is Moraltach because he can destroy any monster on the field. This is a logical reason for why you should not MST, but there are some cases where you will want three MST in your main deck. For example if you go against scraps and they open up with Scrap Factory then you are in trouble if you only play one MST because you will hardly draw it. there are many more times when you will want to play MST but you don't have anymore. This is why you should play MST.
How to use MST
If you do play MST you will want to carefully use it though. There are plenty of Artifact decks around, so you will not want to blind MST. When you blind MST you are randomly going to MST another card. This can lead to a game lose because you might hit a Moralltach. What you will want to do is set your MST an wait until your opponent's endphase to use it and the effects of the Artifact cards will not activate.
