He Who Salts the Earth

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 loses the game if they control ten or
more salt tokens.
