The Long Lonesome Road

The Long Lonesome Road enters with ten time counters on it.
Whenever you attack or block with a creature,
remove a time counter.
If there's no time counters left on The Long
Lonesome Road, sacrifice it and create a 5/5
white Horse creature token, draw 3 cards, and
return an artifact with mana cost 4 or
less from your graveyard to the battlefield.
