Ahkmou, Scheming Trader

At the beginning of combat on your turn, each opponent chooses Kholii or Carving. For each
player who chose Carving, you create a treasure
token. For each player who chose Kholii, place an infection counter on up to one creature they
control.
(Creatures with infection counters can't block. When
it take damage, remove an infection counter from that creature.)
