Rebellion Power Creep
So the next card expansion is set to release around 6 months from now already and it will make no sense for players to get into it after they got totally crushed on Chaos Legion.

THIS. I think I lost like thousands of dollars on CHAOS Legion cards and packs. I'm still salty about them increasing supply by discounting CHAOS packs in a Christmas sale and crushing pre-existing CHAOS packs and cards value.
