Hey! I like your idea about the most efficient cards regarding collection power... Maybe you can do some other collections to make things more interesting and diversified...
For example, the cheapest Splinter (deck) to start with, or the best price-value cards at the moment, or the most efficient sneak (or any other type card) card among all, etc...

I have picked this post on behalf of the @OurPick project and it will be highlighted in the next post!
