Racing is exceedingly rare, as the only time you're likely to be in a race is at the beginning of the game, when you and your opponent have a large number of cards in hand (and thus responses that can interrupt the race), and late in the game, when the race is likely to be short-lived (1-2 turns)
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
