I made a project in Python 3.7.1 that includes classes to create Yu-Gi-Oh cards. This isn't the entire game; it is just the cards itself. I will creaate the entire game later. I wnat feedback on how to improve my code. Here it is:

class Deck(object):
def init(self, main_deck):
self.main_deck = main_deck

 def add_normal_cards(self, card_to_add, all_cards):
 """
 Add monsters, spells and traps to the deck.
 """
 if len(self.main_deck) > 60:
 return "You have to many cards in your deck (60)."
 else:
 card_counter = 0
 # Check to see how many copies of a card there are in your deck. Maximum 3 of the same card. Limited cards
 # will be added eventually.
 for card in self.main_deck:
 if card == card_to_add:
 card_counter += 1
 if card_counter == 3:
 return "You have to many copies of that card in your deck (3)."
 else:
 if card_to_add not in all_cards:
 return "That card hasn't been added to the game yet (" + card_to_add + ")."
 else:
 self.main_deck.append(card_to_add)

 def add_extra_cards(self, card_to_add, all_cards):
 """
 Add monsters, spells and traps to the deck.
 """
 if len(self.main_deck) > 15:
 return "You have to many cards in your extra deck (15)."
 else:
 card_counter = 0
 # Check to see how many copies of a card there are in your deck. Maximum 3 of the same card. Limited cards
 # will be added eventually.
 for card in self.main_deck:
 if card == card_to_add:
 card_counter += 1
 if card_counter == 3:
 return "You have to many copies of that card in your deck (3)."
 else:
 if card_to_add not in all_cards:
 return "That card hasn't been added to the game yet (" + card_to_add + ")."
 else:
 self.main_deck.append(card_to_add)
