These sets are either very strong multicolor sets (Invasion/Planeshift, Khans of Tarkir, Return to Ravnica/Gatecrash, Shadowmoor), sets with great removal at common/uncommon (M11, Conspiracy/Conspiracy: Take the Crown) or strong colorless or colored cards that can reward any draft (Mirrodin/Darksteel and Theros)
Id expect most blue/black decks to pass on this, with red/black and green/black swinging either way

To equip Sunforger for free, add some cards like Ardenn, Intrepid Archaeologist, Armory Automaton, Brass Squire, Kazuuls Toll Collector, Auriok Windwalker, Halvar, God of Battle
The Rocket-owned variant adds a darkness and narrative weight to the design that differentiates it sharply from every other Zapdos card in the hobby, creating a unique piece that appeals to both Legendary Pokemon collectors and Team Rocket enthusiasts
