MST

Quick gameplay post today about Mystical Space Typhoon, one of the most popular competitive YGO cards of all. In many games, in nearly every format I can remember, my opponent has done something like the following:

-Activate MST, set a monster/Spell, pass.
-MST on one random card in a multiple card backfield; card turns out to be something like Icarus Attack, Jar of Greed, or Call of the Haunted (reviving a floater like Card Trooper), which results in a negative transaction for them.
-MST in my End Phase; no follow-up or offensive push on their next turn.

Such plays are among the most common misplays (or at least subpar plays) in everyday YGO. You should not just burn your MST as soon as you draw it, or throw it blindly into a fat backrow. MST is best used to set-up an offensive push, or damage/destruction by battle which leads to advantage. It is also incredibly powerful as a chain to Continuous cards such as Black Whirlwind, D.D.R. - Different Dimension Reincarnation., especially against novice opponents who do not appreciate MST's value as a versatile Quick-play Spell Card.

If you're used to flinging your MST at the first opportunity you have, at any random card...stop and think about it next time. You'll probably wish you had saved it for that Whirlwind or the last Set card in the way of your push for game.
