On-Site Refining

When On-Site Refining enters the battlefield,
create three 0/15 black Morkite Well tokens
(Abilities are printed on the token card).
Dwarf creatures you control can attack Morkite
Well tokens as though they were Planeswalkers.
When you no longer control any Morkite Well
tokens, create five 0/1 white Gold Nugget tokens
and exile On-Site Refining.
Morkite Wells on Hoxxes provide opportunities for
untold wealth - if they can be tapped for their potential.
