My start point is how to force mech/opener loop break, while normal stack won't be too hard to maintain.
Here's my brainstorm:
Insert some duplicating pieces between bags.
More detailed:
Add an indicator at the top (or somewhere), to show when&what dup pieces will come.
e.g. 4xO in coming: 4bags
So as i thought, mech or opener can no longer last, but normal player can get ready for it, won't be a big deal?
Obviously that's all my imagination, I have nowhere to test. How do you think about this?
