It also gives players and collectors who werent involved at the debut of Disney Lorcana the chance to acquire cards from Sets 1-4 that have since skyrocketed in price because of the scarcity of earlier sets like Set 1, The First Chapter
This will consistently pump one of your creatures +6/+6 or even more depending on the turn you cast Summon: Titan
Each card has an ink cost to play it, an ink type, a classification, and of course, instructions and actions on how to use it
