Guardian questions

I took a break from playing and just logged in today and noticed a few things.
How do I get:
Also is crimson for every guardian? Outside of the tiki and the lion I think I’m missing then

Lion is not out yet.

Tiki pack was out a couple of days ago not sure when it’ll come out or if you can get it randomly through other packs.

As for the crimson there are a few out that you can obtain I’m. It sure exactly which ones. I know others will be released eventually but I have no idea when.

Right now the crimsons are ram, exemplar, fractured ward, and vampire bat. The others: snake, watcher, tiger, tiki, and lion are yet to be released.
