Magma Mime

You may have Magma Mime enter the battlefield
as a copy of any permanent on the battlefield,
except its name is Magma Mime, its an artifact in addition to its other types, and it has "At the beginning of your upkeep, put a pressure counter
on Magma Mime, then it deals damage equal to
the number of pressure counters on it to you."
In her heat, I saw the world, in those eyes, the pain.
With both hands I give what will burn.
Be upon me.
