Lords of the Salt Mines

Affinity for Salt.
At the beginning of each end-step, for each time
a player had to discard their hand, had one
of their spells countered, all of their creatures
were destroyed, or at least one of their lands were
destroyed, those players creates a white artifact
token with indestructible named salt.
At the beginning of each player's turn, that
player concedes the game if they control ten or
more salt tokens.
If you're having fun, I'm not!
