# Strionic Resonator Strionic Resonator appeals to collectors interested in casual and Commander formats, where it enables powerful synergies with triggered abilities. The card's mechanical flexibility—copying any trigger for just three mana—makes it a staple in decks built around repeatable effects, which drives collector interest across multiple formats. Most collectors view this as a functional utility piece rather than a chase card. The Magic 2014 printing remains readily available in both nonfoil and foil versions, making it accessible to players building collections. Foil copies command modest premiums, typical for rare utility cards. Collectors generally appreciate Resonator for its role in enabling creative deck construction rather than for scarcity or investment potential.
