Ancient Goldmine

When Ancient Goldmine enters the battlefield, if
you've played it from your command zone, create
a tapped Treasure token for each time it has been played from your command zone this game. (It's
an artifact with ''{t}, Sacrifice this artifact: Add one
mana of any color'')
{t}, Sacrifice a Treasure: Add {c}. If you've
sacrificed an untapped Treasure to activate this ability, add {c}{c} instead.
