I updated the remaining rewards cards based on the data from https://steemmonsters.com/cards/get_details Initially I ran the report on June 14th so draw and burn rates can roughly be calculated by comparing my two charts; however, one extra season reward distribution was included.
Notable remaining cards include Flame Imp at 82.2% draw, Mushroom Seer at 81.8%, Hobgoblin at 82.1%, and Lord Arianthus at 80.1%. Burning stats for some of these higher priced legendary cards is also really interesting. Based on some rough calculations, I assume the cards above 80% drawn will run out in around 75+ days, but that could be quicker if more players join. Also, does anyone know if gold cards count towards the reward card limit or are they a separate category? Let me know if any typos or calculation error jump out! Hope this helps everyone!
Looks like I must have made one typo error back in June when I initially ran it, as Lord Arianthus is now above 80%.
