While Ethan did the hard work of coming up with the original ideas and general deck structure across a couple months, it was Corey's job to take it home
In my mind, Tawnos, Urzas Apprentice is an interesting card that was released at the wrong time
Skithiryx the Blight Dragon is one card that's become far cheaper since the sheet's reprints started to circulate
Since play boosters will match the cost of a set booster, which is roughly $1 USD more than a draft booster, Limited events will probably adjust their pricing to reflect that
Three-mana is also a low cost for this kind of ability, and while the ability is powerful, you can always include cards like Whispersilk Cloak to make sure youre keeping Azusa out of the line of fire
That makes Recoil one of those cards that has a hard time being bad until the point when your opponent has extra lands they can hold in their hand in order to discard them, at which point most decks that run Recoil are either using that as an excuse to crank up the discard engine or more likely happy enough to have survived this long that they don't care
