Mage Tower, A Tower Defense Card Game is an adaptation of the 2013 card game, released the same year. Draft a deck of cards, then battle an AI opponent. Each time you defeat the enemy player, they gain more health. Learn the card pool and draft more degenerate decks as the enemy's power level increases.
As you're battling the enemy, you'll both be fighting off hordes of monsters. Play your own monsters to attack the enemy, cast powerful spells to clear your monster board, and find other devious ways of attacking the opponent.
