the mask
cards do not have a rank (e.g baron, shoot the moon, mail-in rebate)
and 1.5x blind size
-# the original concept was that cards aren't considered face cards (and also negates rank-specific stuff for face cards) but that just feels like a weaker plant
and
the return
debuffs played cards after scoring
and each card has a 1/3 chance to be returned to hand after scoring
honestly i like the return a lot more
