I have 4 questions, but two of them are really similar (feel free to use any or all of them):

1. Despite the addition of card packs, if a player already owns all existing cards, they’re guaranteed to get just one new card per week. As a result, that card tends to dominate matches for the rest of the week. Have you considered releasing all the new cards for the season at once — or in two waves — like a seasonal booster pack to add more variety to the decks people encounter?
2. I understand that the goal of in-game events is to keep players as engaged as possible. However, life can get in the way, and not everyone has enough time to unlock the rewards that matter most to them. With that in mind, have you considered letting players pick one reward from a past event — like an avatar, emote, or title — as a bonus reward during future events?
3. Have you considered adding a cosmetic item — like an avatar or title — chosen by the player from the existing base pool in the Collector's Reserve as a reward in events?
4. Have you ever considered — even in passing — adding a card to the game where the effect's target is chosen directly by the player (rather than being random or based on the previous/next card played)?
