Lone Veteran

Double Strike, Vigilance
Whenever Lone Veteran deals combat damage to a player, you may put two +1/+1 counters, divided as you choose, among up to two target creatures. You lose life equal to the number of creatures who have received counters this way at the end of your next upkeep.
"You may think an old soldier easy to kill. They've survived this long for a reason, though."
