Tact or Friction — Curio City
I have been making Curio decks up and down since my first outing with the card, over a year ago. A simple, mana-free engine that R&D costed just out of the “danger range,” the card can be the glue for so many other decks. As Vanishing and Echo were added to the Standard pool, the possible options for the Curio Use just went up.
