To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of The Fire Crystal's first ability)
In deck building, this balance is called the "mana curve." Each spell has a mana value, which is the total mana cost of a spell
Cards like Calhoun Marine Sergeant and Goofy Super Goof can already grant lore through challenges
You could also cheat fatties out with it late game, so I suppose Id probably play this in a UGx Towns/Ramp deck (though its not that great)
"Can't Hold It Back Anymore" includes artwork that immediately gives an epic feeling of power and royalty, befitting the ice queen, and matching the powerful ability that the card gives players to exert and damage a character
On top of that, the art for the expansion includes some background characters, such as Alice, Perdita, Pongo, Mulan, Mushu, Belle, and Beast, who all look lost in a labyrinth-like forest
