I made a horrible deck choice at the Season One Invitational. If you just look at the results, you could easily make the same one.
I played Esper Superheroes. I should have played Bant Mass Manipulation. It all came down to the last-second coin flip.
Esper Superheroes is a bunch of good cards, but it is fundamentally terrible for the format. Simic or Bant Mass Manipulation on the other hand plays a game that exploits the format perfectly.
Here's how and why.
Traction, Play or Draw
For about the millionth time since War of the Spark was released, here's Michael Majors's Traction article. If you haven't read it, this is the most important piece of Magic theory in the last half a decade and by far the most important piece for War of the Spark Standard.
The other thing you need to understand (that has also been said a million times) is that using removal on planeswalkers sucks. Every reasonable planeswalker in Standard immediately provides a card of value on first use, so if you have to Lightning Strike or Vraska's Contempt them, you are down a card. Even if you use The Elderspell and kill two planeswalkers, you are down a card, probably more because one of those two activated twice. If you want to kill a planeswalker profitably, you need to spend zero cards and do it in combat.
The other threats in the format are also a pain to answer. The cards needed to beat Ghitu Lavarunner, Gruul Spellbreaker, and Command the Dreadhorde are wildly different and they all come with planeswalkers attached.
Also related to this, there's no clean answer to multiple diversified threats.
The other thing that is obvious to everyone by now is that of the top ten or so best cards in the format, about half of them are planeswalkers. Every deck is showing up with them, and you aren't going to just dodge the issue somehow.
With that all put together, you have the following mess.
