IJN. Akashi, Cat Shopkeeper

Whenever a creature dies, you may pay {1}. If you
do, create a Mk1 Bulin artifact creature token
with "Sacrifice this, put a +1/+1 counter on
target creature"
{2}, Sacrifice an artifact: Create a Mk2 Bulin
artifact creature token with "Sacrifice this, put
a +1/+1 counter on all creatures you control"
"There’s always some nice stuff among the litter."
