Summer - Chaos Origins (CORI)

Once per turn: You can place Season Counters on this card equal to the number of your opponent's unused Main Monster Zones. Once per turn, when your monster declares an attack: You can inflict damage to your opponent equal to the total number of Season Counters on this card and "Spring" in your GY x 400. Once per turn, during your opponent's End Phase: You can take 1 Field Spell from your hand or Deck that you can place a Season Counter on, and place it face-up on your field (but neither player can activate its effects this turn), and if you do, place all Season Counters on this card on that card.
