Sure. Despite the fact that I could not get into such a massive position, I did try and secured a few k of SPS while spending a bit for packs and cards, too. It was quite a stretch reaching Gold League requirements of Collection Power.
I received more promo cards while I had 10 % to 30 % chance or something than when I moved above the 50 % mark. They stopped coming before Spirit Hoarder. Mentioning that dude because I really liked the card and spent a bit on buying a couple off the market.
This is my game. A couple of this here, a couple of that there...
In terms of USF, DEC and SPS made quite the dive, afterwards but in terms of relative Card-purchasing power, they stayed close to the same. A matter of time and patience now to see if we hit another wave of awesomeness.
Spirit hoarder is a bit of a street sleeper that many people underrvalue!
When it comes to cards, I have made a lot of mistakes in my approach - as I haven't even tried to fill holes with any kind of systematic approach, it is all just randomness...
This is something many people have missed. Unless you need money IRL from it, all is well :)
