Change new board necromancer selection #86
Description
When a board resets, you compute for each type of necromancer:
m=# of necromancers of that type that side has in play, chosen, across all boards
n =# of necromancers of that type that side has in selection (ie a different board reset and locked in their choice yet)
o =# of necromancers of that type that side has had previously in play (including the resetting board), but no longer.
You then rank (increasing order) the types of necromancers by m+n, then m, and then o, and then randomly. You take the 3 types with the lowest value, and add them as possible selections for that board.
