Not long before in Magic 2015, an Enchantment called Crucible of Fire was reprinted. This 4-mana Enchantment gives all of your Dragons +3/+3. Dragon Tempest makes for yet another major enabler recently printed for building around Dragons. Putting the effect of Scourge of Valkas on an enchantment is truly powerful. While it's never seen serious Constructed play, it's become a casual favorite among Dragon players. It's especially good in Dragon Commander decks. Despite being $0.75 on the TCGPlayer marketplace, it's over $2 on Amazon. This is definitely one to keep around in the trade binder, because you'll never know when this might be a few dollars, eventually.
