St. Patrick's Day Special Edition Cards From Superhero City

Superhero City is celebrating the luck of the Irish with St. Patrick's Day Special Edition cards that include Scream of the Banshee, Dance of the Leprechaun and Descendant of Lir (I need two more Merit Points for the second one):

They are also having a 25% sale on Celtic equipment that includes Aequitas Ring, Shamrock Core armor, Celtic Cross Amulet, Veritas Ring and Dagda's Harp. You can also buy/find green beer and clovers for clovers for energy boosts (I only found one clover so they are very rare).
