When Marvin is using his "card magic", the suits from his mask will appear on his forehead, glowing teal. This happens to "tie his energy" to the cards in a symbolic way. Think of Marvin like a power outlet- by himself he can cast a few spells at once just fine. However, as he needs to cast more then one at a time, that's where his cards come in. The cards are like those power strips you plug into the outlet. Now, he has more "outlets" for his magic, allowing him to cast more spells at once!
