Though I shouldnt be surprised, Im still pretty confused as to why Spellskite hasnt dropped much in price
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)
This deck uses your creatures as resources, with Orah and your other clerics letting you constantly recycle your graveyard for powerful value plays
The price of an Energy Switch (Incandescent Arcana [S11a] 093/068) card is 3,080 JPY (~US$20)
At the complete other end of the scale of those big mana investments are the remaining fast mana options that arent gamechangers
Outside of Bladewing the Risen, you dont really see many Rakdos dragon decks, and I think Rivaz is a sweet Commander for those decks
