Mental Misstep was banned in the initial Modern banned announcement, based mostly on how it played in Legacy, where it essentially pushed one-mana plays out of the format and made most decks 56 cards, since everyone had to run Mental Misstep, not so much because they wanted Mental Misstep in their deck but because they needed to be able to counter their opponent's Mental Missteps
Distribution and quality of overall cards (ramp, interaction, draw): The deck has about 10 ramp cards divided among artifacts and creatures, though most creatures only colorfix for green, even though mana pips seem quite evenly distributed in the deck
I also appreciate the toughness boost on Secret Plans, which enables you to attack into or block Courser of Kruphix, one of the power cards in our new Standard, and I very much love the card-drawing trigger when you flip a morph card
This spell only touches your creatures but doesnt remove any of their abilities
