but you got a problem : into the pile you have the
Chamber Sentry down in the graveyard due to the mill (if I understand well)
So in reaction, the opponent get the priority again
before the status changing, so you are exposed to a lot of effect ( like
Settle The Score for example)
But the idea is good, I just mark a point, if your
Chamber Sentry is a Zombie in the graveyard, he losing the Artifact status for a while so into the pile, so
Diligent Excavator doesn't work at a point, but I need to have another point of view IMO (Same thing with
Raff Capashen, Ship's Mage)
But good job, BTW you got my Like...
