I heard Mall-o-Matics will be officially released in 19746, so I'm looking forward to them.
They're in some 4-digit levels now and I saw them in some levels. Also, there were two long droughts of new blockers.
What new blockers will be introduced post-20K? Which trait will those new blockers have? Citrus chews are non-event blockers, though introduced by selective redesigns, so that's one candidate to be seen post-20K!
