So many I wouldn't know where to start, in both directions, but primarily newer=better (sadly) when it comes to creatures w/ abilities. White has the Best 1 cc creatures imho. What is missing from this discussion and matters is rarity. It isn't fair to a Common vs a Rare even with the same CC. Is it really fair to compare Mother of Runes to Tundra Wolves or Devoted Caretaker, or Soul Warden to Savannah Lion? You have to look at the environment at the time of printing, cards seem to gradually get better in some categories, which has to happen in order to keep us old timers buying.
