They will be available by the end of the month. As for the raid cards (like Valentine's raid), I'm currently working on some sort of "singleplayer raids" :)
So don't worry, everything you've missed will become available in the future! And I know the "Llama Mark" Shop might already feel like a huge commitment, so I'm also thinking about making them event mission rewards. If everything goes as planned, the next event will start later this week.
