1: Once a day being able to block playing 1 class! Fed up of queuing into 100 shamans hey presto you don’t! (I’m aware and ok with this being on casual mode)
2: A pool of 4 pre selected cards that you can swap into your deck at the mulligan phase for added strategic play! Facing a warrior swap out a card add Elysiana!
And finally
3: AUTO SQUELCH
That game is balanced around classes being missing but as you added the casual implementation then that’s a fairly reasonable suggestion (prefer full tournament mode when you could back a class/cards etc)
They problem with that is that it kills off a lot of cards (I.e they will always be hard countered so you can’t play them) plus it takes away from the skill of deck building/reading the meta.
They should have added that years ago. Doesn’t really bother me as I pretty much always have the game muted but strange that it isn’t an option.
