Thanks for the contest!
What I'd like to see on the wax sale:

1. a well thought out approach to bots and flippers so they don't take the majority of the drop. Maybe something like a well verified whitelist with a tight cap on how many people can buy for the first x hours. (Just please don't make this dependent on how active someone is on the discord, or it'll lead to a lot of spam!)
2. right now on hive its a bit hard to tell which card is which rarity unless you filter by rarity and then see what cards show up. Hopefully this will be easier to indicate on wax / atomic hub. Splinterlands didn't (maybe still hasn't?) put in good filters on atomic hub so its very hard to search by rarity, but i hope exode will!
3. splinterlands does have a good portal mechanism for moving cards from wax to in-game. It would be nice to see a similar exode atomic hub page.
