Mythic Booster
First, I like the concept of mythic boosters a lot, it's a great way to acquire remaining cards of a mostly collected set. But imho there is some room for improvement...
- Expand it to all sets
There a still plenty of sets without mythic packs. Mostly older sets and some of them are really mythic-heavy like the both remastered sets, but also new stuff like Alchemy expansions you drop every set. I don't see any good reason why these sets shouldn't have mythic packs available as well.
- Remove the opportunity to get a rare wildcard in mythic packs.
Most players still might have usage for rare wildcards, but when you purchase a mythic pack you expect to get a mythic, or to be even more clear here, it is your explizit demand to collect a mythic card for your collection. Therefore getting rare wildcard feels really bad and like a scam.
Mythic wildcards are perfectly fine in mythic booster, but rare wildcards are simply not.
