I think it may be a stretch to assume there is going to be a full cycle of these. The black and red ones may well have been designed to fill holes in the set and that's it.
Really hoping they finish out this cycle with pushed cards in white and blue. At this point it's probably pretty unlikely, but we have had some great cards spoiled at the end before...
I thought we were going make it without a single person saying that it's not strictly better. I guess you couldn't help yourself
