For question 1.
So far I have been using artifacts and face down ones on the table and making them "hover" if they are face up and active. Plus there are some abilities that can target face down artifacts and is easier to see visually.
As for the set aside same answer for the one above prefer on table but similar reason so they can be seen easier for other players on the table.
For question 2
I would be okay with just the unlimited and the 2 liner Lost Soul (from limited) cards. Maybe A and B deck if anyone really wants to play them??
Also for the Land of Bondage I think the Lost Souls should be on the table so it is easier for other players to see and as sites can not go in the LOB.
Maybe all the tabs in Lackey should just be used for player's LOR , deck , discard pile , hand , removed and all the other tabs etc similar to Rts.
Just my thoughts on it.
Any other thoughts on Lackey anyone?
