Like most Magic: The Gathering cards, the value of Encroaching Dragonstorm depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Tarkir: Dragonstorm)
One of the best ways to protect your collection and show it off at the same time is a binder, and believe me when I say that youve got tons of options
And as with any other mass token-producers on this list (or otherwise), that translates to a ton of valuable triggers from your tribal support cards
Though I shouldnt be surprised, Im still pretty confused as to why Spellskite hasnt dropped much in price
As the ability resolves, you create a token copy of each card
Outside of Bladewing the Risen, you dont really see many Rakdos dragon decks, and I think Rivaz is a sweet Commander for those decks
