Bloodmoor, they've been coming out with new cards as they always have. At the rate of 4 per 2 weeks, with an occasional (about once a month) single extra. It's really not that fast.
The New Blood packs
(if that's what you're referring to by newbie packs) have always contained the last 35 characters that came into Clint City. When a new character comes in, it bumps the oldest out of the pack
. For example when the next 4 characters come in, they will bump Lewis
, Marlysa, Ombre, and Selsya out of the New Blood Packs
. At which point they will only be available in their clan specific packs
or the 8 card pack
(Action for Lewis
and Marlysa, Danger for Ombre and Selsya).
