Looking at the $10 purchase from just an investment aspect. It would seem that its still a great deal to purchase the $10 starter set as you already got what I consider a good return on that investment. It will be interesting to see what cards you get going forward in your daily and season rewards. You may come close to making near your $10 back in a single season. There isn't too many investments you can make that give your invested amount back in 14 days.

If you don't get the delegation from SM there is a section in discord that is specifically for RC issues. I would recommend posting that you ran out of RC in that section if you don't receive it automatically.
