I might be the only person who thinks the "Restricting Mistep will make decks better against workshops" is a foolish argument.
Workshop needs restricting. They have a penchant for printing artifacts iwth a 'fair' mana cost, while only thinking of Standard and Limited. The Workshop deck, with 1 workshop, is still a threat. How many times has someone lost to a workshop deck when they didn't even draw workshop? I know I have.
