To me the new card system looks more interesting than what we currently have. In the trailer cards seem to still be random and different. At least they are different arcanas in both instances of draw and also have different outlines, which to me implies, that their effects are not always the same, but that drawing cards only guarantees the same amount of cards from each category.
Or has it been confirmed that every 60 seconds we will in fact draw the exact same 4 effects every single time, and the different aracanas and outline colors are merely decoration?
