You CAN Play Type I #95: Sifting Through Scourge, Part V – Sorceries and Instants
Decree of Annihilation’s cycle effect is incredibly powerful, but that makes you ask which deck it fits in. Obviously, it’s not something aggro, aggro-control and combo need. As for control, Armageddon was used in Type II to keep an opponent’s mana count down while a big creature beat down or an artifact-based lock held him tight. The 7-mana price tag attached to uncounterability precludes this. That leaves you with blue-based control decks with a red splash, but why would these mana-intensive decks want to wreck their own mana and hurt themselves more? Thus, I don’t think you’ll need to be sideboarding Stifles anytime soon.
