For starters I think the numbers going up is inflating demand on even rental cards. This week I've had 3 cards yanked out from under me so they could raise the prices. That's one issue. Another is, the reason DEC is going down so little compared to SPS. DEC/pack/land markets are going to be cut-throat with the influx of people wanting the "free SPS" from the airdrops rather than buying them. Meanwhile since fewer people are buying, it's easier for those with bots and or a fair amount of resources to crash the SPS market, so they can buy more and more cheaper and cheaper. The bigger the influx, the more this will all multiply.
