This card's Elemental Blast attack is similar to the attack of the same name possessed by Neo Genesis Lugia. The only real difference between the two is the 110-damage difference in base power. Another difference is that the Unseen Forces card states "energy" while the Neo Genesis card states "energy card".
Silver Sparkle's name references Lugia's status as the game mascot of Pokémon Silver. Elemental Blast is a reference to Lugia's role as the master of the legendary birds, requiring one energy each of Articuno, Zapdos, and Moltres's TCG types to use.
