So let me first point out that I've tested/played Durant extensively against some of the top-rated players in the US.
- Durant takes a lot of skill to build.
- Durant takes almost no skill to play.
Using a good list, there hasn't been a game playing Durant for me where it doesn't feel like autopilot. Sure, using Mischievous Trick takes some "skill," since determining what's in your prizes and knowing what to pull out of your prizes can be a skill. However, that's more memory-related, and I'm not convinced that any of the top players would have a problem using Rotom correctly.
You're forgetting twins. Twins is such a skill intensive card. You get to choose 1 card from your deck (since the other one will almost always be a 2nd twins), what will it be? Do you want to go for a Revive so you can keep devouring for 4, or should you go for a Catcher and try to stall for time? Maybe.. you should pick a prism energy, so you can snipe your opponents Zekrom?
There's all kinds of decisions you have to make when playing Durant. You have to know when to spend your resources, and when it's better to just save them for later. Junk Arming for a Crushing Hammer is usually not worth it, but in some situations it might be. It's all up to you, and one wrong decision could cost you the game.
And also. The deck list. Building a Durant list is so hard and it takes some real skill to build a list that can compete in the current format. Sure, building a deck isn't the same as playing it, but they are connected.
The reason everyone and their mothers could win so much with Durant in the early NV format was because few people knew how to play the match-up. Most people thought of it as a troll deck, a bad deck designed to frustrate people and nothing less, and they would end up losing because of that.
Nowadays, everyone knows how to play the match-up, so people can't just go "hurp derp I wanna win a tournament, time to go to town Durant", they have to actually be really, really skilled at playing the deck to win. And even if they're are, they're not in for any easy victories since Durant struggles a lot against ZekEels.
It's not all about devouring anymore. Turn 1 Collector and then Devour the entire game won't win you any games if you're not good with the deck.
I'm guessing most of you who keep insisting Durant takes little or no skill to play haven't played the deck enough, played it but failed miserably, or have been losing too much to it so you feel the need to hate on it.
