I believe they said the seasons will go for 2 months each and so this season will end on the end of this month or the beginning of next. Then they plan to roll out 20 new cards each season change but I don't know if that applies to the seasons in the beta still or if they have readjustments they want to make on existing cards. What I would really like to know is whether or not the cards will be added to the existing keg, I'm holding onto my scraps for dear life thinking that the keg might just be really big one day and have every card in it so terrible RNG to pull a card you want out of buying kegs.
Don't quote me on this, I'm usually the last with the know how and I'm still trying to locate where this next patch is, not sure if it was just part of the livestream. but yeah so...
